With continuous grab on, in 2+ window setup, when RMB-dragging an object in a 3D view of a not active (not frontmost) window, mouse cursor was stuck, with no escape.
Cursor grab must be done by the window that is key (able to receive mouse move events).
When the user double-clicks on a document file in the Finder, OSX doesn't simply give the filename as a command-line argument when calling Blender, as it is done in other OSes.
Instead, it launches the app if needed, and then sends an "openFile" event.
The user can also open a document file by dropping its icon on the app dock icon. But as this is not real Drag'n'drop, I've renamed the Ghost event to a less confusing "GHOST_kEventOpenMainFile" name.
DND Ghost wiki page updated : http://wiki.blender.org/index.php/BlenderDev/Blender2.5/DragnDrop
Cocoa can still send events (tagged with the correct NSWindow handle) after having sent the window deactivate event.
This caused these events being discarded as there was no active window for GHOST_WindowManager.
Fix is to use this NSWindow handle to retrieve the target window and correctly push the event.
E.g. of effects of this bug: OSKey modifier stuck after having invoked Spotlight through its shortcut (Cmd + Space). This gave the impression the Blender window has not got focus back for the keyboard.
Ton, can you confirm if this fixes the "Cocoa window loses focus permanently on using Spotlight" issue you found ?
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
There are calls to define drag-able images, ID blocks, RNA paths,
file paths, and so on. By default you drag an icon, exceptionally
an ImBuf
- Drag items are registered centrally in the WM, it allows more drag
items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts
the mouse event to an EVT_DROP type. This event then gets the full
drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps
you can make a "drop map" this way, which become 'drop map handlers'
in the queues.
- next to that the UI kit handles some common button types (like
accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
- poll() = check if the event drag data is relevant for this box
- copy() = fill in custom properties in the dropbox to initialize
an operator
- The dropbox handler then calls its standard Operator with its
dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit
on mouse-over. In case the icon is a button or UI element too (most
cases), the drag-able feature will make the item react to
mouse-release instead of mouse-press.
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works
too. I've added code that passes on mousemoves and clicks to other
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an
Image ID... keep this in mind. Sequencer for example wants paths to
be dropped, textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're
part of the UI and editor design (= how we want an editor to work), and
not default offered configurable like keymaps.
- At the moment only one item can be dragged at a time. This is for
several reasons.... For one, Blender doesn't have a well defined
uniform way to define "what is selected" (files, outliner items, etc).
Secondly there's potential conflicts on what todo when you drop mixed
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip,
should be represented in filewindow as a single sequence anyway.
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it
could show the operator as a sort of menu, allowing arrow or scrollwheel
to choose. For time being I'd prefer to try to design a singular drop
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that
detects an object (type) under cursor, so a drag item's option can be
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled,
while WM event code tried same. Added new OPERATOR_HANDLED flag for this.
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
(for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review...
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS
into Blender window. I've noticed this code is unfinished for Macs, but
seems to be complete for Windows. Needs test... currently, an external
drop event will print in console when succesfully delivered to Blender's WM.
- transform default scale was too hight, calls to random were inconsistant. (fault of own modif's)
- cmake openal include was added twice on recent commit.
- fix race condition between applicationBecomeActive, and WindowBecomeKey events that discarded the modifiers keys status change event message
- workaround for a 10.6 bug that made the Cmd (oskey) modifier erroneously on.
Note: AA is still disabled due to AA creating problems for selection tools. If you must, set AA to 2 or 4 in wm_window.c where the GHOST window is created (line 317).
- 2 fingers scroll (MOUSEPAN / GHOST_kTrackpadEventScroll event) pans/scrolls the view
- 2 fingers pinch (MOUSEZOOM / GHOST_kTrackpadEventMagnify event) zooms the view
And in 3D view:
- alt + 2 fingers scroll rotates the view
- 2 fingers rotation (MOUSEROTATE / GHOST_kTrackpadEventRotate) orbits the view.
The implementation uses a new GHOST event type: GHOST_kEventTrackpad, that is then dispatched as Blender MOUSEPAN, MOUSEZOOM
or MOUSEROTATE events.
This is currently fully implemented for OSX (GHOST Cocoa fires the new events), with auto-detection of the source peripheral, so that a regular mouse still sends MOUSEWHEEL events.
Added GHOST_TUns16 numOfAASamples parameter to GHOST_CreateWindow to specify the number of AA samples (null if no AA wanted)
Implemented it in the cascade of GHOST classes.
Full implementation currently done for OSX/Cocoa, stubs for other OSes.
Moguri : it's ready for your win32 implementation !
Note that fallback to a non AA window (if gfx card doesn't support AA) is done inside GHOST OS specific layer, so that blender windowmanager still gets its window created properly.
On X11, the opengl context was destroyed when closing a window. This lead to
the text and icon textures being lost (among other things), now the opengl
context is kept like on Win/Mac.
* added some new variables (mostly the same as with scons):
- USE_COCOA: use Cocoa for ghost (defaults to true)
- MACOSX_ARCHITECTURE: can be ppc, ppc64, i386, x86_64. By default this is the host architecture
(ppc for PowerPC Macs, i386 for Intel Macs). In theory this allows to cross compile blender for
a different architecture, though cross compilation only works on Intel Macs, because makesdna
and makesrna are built for the target architecture.
For a 64 bit build, set MACOSX_ARCHITECTURE to x86_64 (Intel) or ppc64 (PowerPC).
- MACOSX_MIN_VERS: minimum OS X version to run blender on (10.4 for 32 bit builds, 10.5 for 64 bit builds)
- MACOSX_DEPLOYMENT_TARGET: needed by the linker to create an Application targeted for a specific
OS version (defaults to 10.4 for 32 bit builds, 10.5 for 64 bit builds)
- MACOSX_SDK: path to a specific SDK. currently not used
- USE_QTKIT: use QTKit instead of QuickTime (defaults to true for 64 bit builds, as using QTKit
is mandatory in that case))
* use the same compiler flags as scons
* default compiler now is gcc-4.0 when building for 10.4 and gcc-4.2 when building for 10.5
* extract $(LCGDIR)/release/python_$(MACOSX_ARCHITECTURE).zip to Application bundle. This might
break building on 10.4, to fix that, rename $(LCGDIR)/release/python.zip
When compiling blender, only MACOSX_ARCHITECTURE might be of interest, as it allows doing 64 bit
builds (or 32 bit PowerPC builds on Intel). All other variables are then set to reasonable defaults.
For current users of the Makefile system, this commit shouldn't change much.
This nice patch by Matt D. (matd in #blendercoders) adds three nice features that can be seen already in the other supported OSes:
* minimum window size: to prevent some bugs with the window manager of Blender, system windows cannot be resized smaller than the minimum size.
* Continuous Grab is finally in Windows! Default settings since alpha 0 already have the feature enabled by default, so grab a new build and enjoy :)
* GHOST support for drag and drop added. This prepares Blender for drag and drop from OS -> Blender. Currently not very useful, since wm needs to be readied for that. But it does work (do BF_GHOST_DEBUG=1 build and drag a file onto a Blender window).
Thanks Matt D.!
Note: this works fine when running under 10.6, even if compiled with an older sdk
Under 10.4/10.5, workaround remains to assume no modifier key is pressed when the user restores the focus to the application
The carbon GetModifierFlag function (to get the current modifier keys status) is reimplemented in cocoa only from 10.6.
So we need to use a workaround to get the correct modifiers when blender application gets focus back. Current one is to assume no modifiers.
This at least fixes the issue when blender has been hidden using Cmd+H. The Cmd modifier was still seen as ON until the user pressed again on it.
Symptom: first button drag gets stuck on values.
Cause: Buttons didn't set grab bounds, to use the whole window. But Ghost didn't do anything in that case, it left the bounds value as is. It only affected the first cursor grab, because cursor ungrab sets it to -1, which forces it to use the whole window size (checking every mouse move) for subsequent grabs.
Solution: When NULL, init bounds to window size (and don't query every mouse move).
Need to stop accumulating warp coordinates after the first cursor warp (store time of new generated event and skip warp for events time smaller).
There's some interesting X11 code in there, if people are curious.
- Drag'n'Drop events are now correctly signaled to the main loop for dispatch (these events were directly handled in cocoa callbacks without notifying the process loop)
- Fix timestamping of events & add debug print of drag'n'drop events.
The dragging sequence is performed in four phases:
- Start sequence (GHOST_kEventDraggingEntered) that tells a drag'n'drop operation has started. Already gives the object data type, and the entering mouse location
- Update mouse position (GHOST_kEventDraggingUpdated) sent upon each mouse move until the drag'n'drop operation stops, to give the updated mouse position.
Useful to highlight a potential destination, and update the status (through GHOST_setAcceptDragOperation) telling if the object can be dropped at the current cursor position.
- Abort drag'n'drop sequence (GHOST_kEventDraggingExited) sent when the user moved the mouse outside the window.
- Send the dropped data (GHOST_kEventDraggingDropDone)
- Outside of the normal sequence, dropped data can be sent (GHOST_kEventDraggingDropOnIcon). This can happen when the user drops an object on the application icon. (Also used in OSX to pass the filename of the document the user doubled-clicked in the finder)
Note that the event handler is responsible for freeing the received data.
And the mouse position is sent directly in blender client coordinates (y=0 at bottom)
The GHOST_setAcceptDragOperation(TRUE) call must be placed before the user drops the object for it to be accepted.
Current handled data types :
- Text string
- Array of filenames (full paths)
- Bitmap image (not implemented yet)
- QuickTime export fixes.
Note that QuickTime export still crashes because it tries to open a "codec settings" dialog from the rendering background thread (and not the main/UI thread).
One quick fix may be to move the movie export initialization out of the render thread back into the operator function.
But a cleaner way would be to get rid of such a carbon/win32 dialog and place the codec settings inside blender interface
(additional fields in the output panel as it is currently the case for other file formats ?).
- replace libtiff by calls to Cocoa services to load/save tiff files
(Libtiff, dynamically linked is not distributed with OS X, and would have had to be shipped for all four architectures)
The imb_cocoaLoadImage & imb_cocoaSaveImage are generic towards the bitmap format, and thus can handle TIFF, GIF, JPG, JP2000, BMP and raw camera formats (read-only for these), even if today only TIFF is used as the other formats are already handled.
- CMake updated
- scons updated (Thx to Jens Verwiebe)
Fixed gcc-4.0 compile error (cocoa)
Updated scons to build cocoa (32bit & 64bit) (Thx Jens Verwiebe for the patch):
- make sure right python is unzipped to app-bundle ( printing information at the end of compiling )
- make sure arch-setting appends needed flags ( depending on OSX-version obsolete sometimes but harmless )
- link correct frameworks depending on gfx-api ( cocoa/carbon)
- conscript prepared for cocoa objC-files
- link to openAL-framework, using the headers from blender-lib + the symbols in framework
Usage instruction:
The default build is Cocoa 32bit.
To change it, copy config/darwin-config.py to user-config.py in the blender folder, and edit:
- WITH_GHOST_COCOA & MACOSX_ARCHITECTURE variables to select cocoa/carbon, and the arch (i386, X86_64, ppc, ..)
- the libs options as usual
- use Cocoa function to convert keys character value to isoLatin-1 encoding instead of the translation table. Works better with international keyboards
- enable stereo GL option
- fix source/creator CMake file to remove unneeded folders in the app bundle (the __MACOSX stuff). (Thx jensverwiebe)
- tablet : fix pressure retrieval => value sliding now works with tablet, UV-painting is pressure sensitive, and no more crash when clicking on window minimize button with the tablet
- update CMake file to remove unneeded folders in the app bundle (the __MACOSX stuff). From Jens' patch
- fix windowDidResize event not forwarded in some cases on 10.6
- fix crash on repeated Cmd-Q + Cancel quit actions
- place stub for .blend drop on blender app icon
Auto save is now working again in 2.5. It will also remember now what
the location of the original file was when recovering it, so that
library links still work and saving the restored file does not save to
the temp directory. There is also a new Recover Auto Save operator
which will open the filebrowser in the temp directory and show the
auto saved .blends.
Implemenation Notes:
* Timer storage was moved from window to windowmanager, so we can have
windowmanager level timers too now, doesn't make sense to have
autosave timer attached to a particular window.
* FileGlobal now has a filename field storing where the file was saved.
Note that this is only used when loading a file through the recover
operators, regular file read doesn't use it, so copying the quit.blend
manually over the original file will still work as expected.
* Jobs timer no longer uses operator now, this seems more like an
internal thing, changing keymaps should not make it possible to break
the jobs manager.
* Autosave is postponed by 10 seconds when a modal operator is running,
e.g. transform or file browsing.
* Moved setting G.sce in setup_app_data before depsgraph updates, these
can use the filename for pointcaches.
- fix 10.6 API used in window resizing callback causing crash on 10.5 systems (Thx Jasper Mine for the bug report)
- implemented min window size enforcement to prevent tiny windows messing up blender's internal ui layout (same as done by Campbell on X11, is a partial fix of bug #19550)
- added (commented) code for enabling multithreaded opengl (this optimization is here for experimental tests, not for mainstream, so bleeding edge testers would want to uncomment the three "Multithreaded opengl code : uncomment for enabling" sections)
- when wrapping 2 mouse events were added.
- on release blender still had the last event (possibly outside the screen), where menus would fail to show. Add a mouse event by calling XWarpPointer with no movement when leaving grab.
- Use an enum for grab modes rather then boolean options.
-- GHOST_kGrabNormal: continuous grab userpref disabled
-- GHOST_kGrabWrap: wrap the mouse at the screen bounds *
-- GHOST_kGrabHide: hide the mouse while grabbing and restore the mouse where it was initially pressed *
GrabWrap is nice for transform and tools where you want some idea where the cursor is, previously I found both restoring the mouse at its original location and restoring at a clamped location was confusing with operators like transform, wrapping is not ideal but IMHO the best of a bad bunch of options.
GrabHide is for numbuts, where restoring the mouse at the initial location isnt so confusing.
- Small changes to make ghost_cocoa compatible with 10.4 + gcc4.0 (the initial goal was to be 10.5+ compatible, but 10.4 is finally also possible)
- Main window title is now in Apple document window title style (proxy icon + filename)
- fix for top menu "Blender" sub-menu not anchored correctly in 10.5
Instead of capturing the display and all user input (video game mode), the mechanism is now to hide dock & menu bar, and enlarge the window made borderless to cover the whole screen surface.
Thus all OS X window management features remains available (other windows,multi screens compatible, process switching, expose, spaces, ..)
- Useful for dragging buttons to the far right when theyd otherwise hit the screen edge.
- Useful for transform though probably NOT what you want when using the transform manipulator (should make an option).
- When enabled, number buttons use this as well as a different conversion of mouse movement
float numbuts: mouse 1px == 1-clickstep
int numbuts: 2px == 1 (tried 1:1 but its too jitter prone)
details...
- access as an option to GHOST_SetCursorGrab(grab, warp)
- Currently all operators that grab use this, could be made an operator flag
- only Ghost/X11 supported currently
(Mostly for very early testers)
Cocoa uses coordinates with y=0 at bottom : updated wm_window.c and wm_event_system.c for COCOA build to avoid double conversions in response to mouse move events and GHOST_getCursorPosition
Known limitations:
No fullscreen support
Font issue in preference panel
libSDL uses some Carbon functions
- Window creation at preferred size
Implement in Ghost the use of Cocoa functions to get the maximum visible rect (size and position) for the window contents (all screen excluding dock, top menu, and window title bar)
Thus Apple specific code in window creation (wm_window.c & wm_apple.c) is no more needed => removed in case of Cocoa build
- Alert on exiting despite unsaved changes
Add to GHOST method to maintain an all platforms (not apple specific anymore) status on unsaved changes
Update GHOST_SystemCocoa to use this for asking or not user to confirm exit without saving changes
GHOST*Cocoa.mm & .h files creation
First Cocoa version of GHOST_SystemCocoa.mm
CMake files update to allow optional (WITH_COCOA option) Cocoa version build - disabled by default
SCons files are not updated to allow Cocoa build (the ghost .mm files)
Tested in X11 where its fairly confusing.
buttons 4 and 5 are used for the wheel which is well known, but it seems 6 and 7 are used for horizontal scrolling, my mouse assigns the extra 2 buttons to events 8 & 9.
So the X11 events used for buttons called 4&5 in blender are 8&9 in X11.
The mouse buttons can be re-ordered like this once xorg starts (swaps 6,7 with 8,9)
xmodmap -e "pointer = 1 2 3 4 5 8 9 6 7"
Couldn't test Win32, Apple not supported.
If someone wants to add horizontal scrolling its quite easy.
--- 2.4x log
use functions to detect stylus and eraser from the wine project, supposed to work with non-wacom tablets too (searches for wizardpen & acecad as well as 'stylus').
2.4x did an exact check on the name, 2.5 does a case insensitive search on the type.
This does a case insensitive check on both the name and type.
close the devices on exit too.
- last commit, missed include for rna_object_api.c & bad args to find_basis_mball
- use enum for GHOST tablet type None/Stylus/Eraser, had duplicate definition for these in C. Only tested X11, may need to cast to an int for other OS's.
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
* Hopefully fixed X tablet support. The name string was not a reliable way of finding tablet anymore, so now we get the type string and search it for 'stylus' and 'eraser'. Still not very robust, but without UI I don't see how to do better.
- CMake, use FIND_PACKAGE(Freetype) for unix/linux
- Only link with libdl.so on linux
- use statvfs rather then statfs for netbsd (size of statfs wasnt available)
- add x11 include path with ghost, glu.
- ghost data wasn't being freed (added wm_ghost_exit() call to wm_init_exit.c)
- GHOST_EventManager wasn't freeing GHOST_IEventConsumer's
- ghost/X11 wasnt calling XCloseDisplay(), some junk from X11 wasnt being freed
- ghost/X11 XAllocNamedColor wasn't freeing the colors when done making a custom cursor.
* Pass on mouse location on window leave/enter too, fixing some
issues with button highlights and tooltips.
* When a modal operator runs, grab the mouse cursor so that for
example transform still works when you move your mouse outside
of the window, previously it would just stop then. This is
automatic now for all modal ops, perhaps not always needed?
* Fix for a trailing button highlight issue.
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
* Added new modifier tab.
* Fixed problems when no object was selected after delete.
* Added initial Armature, Bone, Curve and Font panels, by William Reynish (Billrey). Thanks!
* Small RNA changes
* Commit revision 20240 and 20268 from trunk. ("Mouse wheel zoom lost after rendering.")
1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
the old BMF api.
I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.
MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
Always have to link/include the freetype2 library
Remove any reference to libbmfont
Remove any reference to libftfont
Remove any reference to libbftgl (or libbFTGL)
Commit patch [#18597] Blender's text editor cant paste from SciTE in linux
Submitted by Campbell.
I made some changes to cleanup a little the code, atoms are now in the
System class. The getClipboard_xcout try to convert/request:
1) Request for UTF8, if fail
2) Request for COMPOUND_TEXT, if fail
3) Request for TEXT, if fail
4) Request for STRING
Test here with SciTE Version 1.77, firefox, xterm and text editor working
with both library's gtk/qt and all work fine.
Some WM send a WM_TAKE_FOCUS event before the window is really mapped
(for example, change from virtual desktop), because of this, the call
to XSetInputFocus fail and close Blender.
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
the text editor. It's Bitstream Vera Sans Mono. This is the
default gnome terminal font, but it doesn't fit entirely well
with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
This needs especially a way to start editing the text field
immediately on open still.
* Operators are independent of the actual space when possible,
was a bit of puzzling but got it solved nice with notifiers,
and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
* New, Open, Reload, Save, Save As, Make Internal
* Run Script, Refresh Pyconstraints
* Copy, Cut, Paste
* Convert Whitespace, Uncomment, Comment, Indent, Unindent
* Line Break, Insert
* Next Marker, Previous Marker, Clear All Markers, Mark All
* Select Line, Select All
* Jump, Move, Move Select, Delete, Toggle Overwrite
* Scroll, Scroll Bar, Set Cursor, Line Number
* Find and Replace, Find, Replace, Find Set Selected,
Replace Set Selected
* To 3D Object
* Resolve Conflict
* add preliminary support for building Blender on 64bit Windows with _msvc_. The SConstruct should automatically detect if you are on a 64bit Windows and if you have that 64bit build is assumed. If you're not, 32bit build is assumed.
NOTE: this is still very much wip, so your mileage may vary. Do please report on b25 taskforce ML in case of trouble.
NOTE2: many of the libs are being linked in statically
NOTE3: hopefully I didn't break anything for other build platforms (mingw, linux, osx).
NOTE4: comes after NOTE3
The crash is caused by calling XGetWindowProperty when xevent.xselection.property is zero.
Not a proper fix because clipboard can paste the data without trouble.
Bugfix in OSX ghost!
The GHOST_TWindowState was set to 'invisble' always... which is a
state now handled correctly in Blender. It caused the window to not
refresh when resizing.
Removed AUX buffer for OSX, was taking too much OGL memory,
and since AUX was not used for other platforms, its benefits
faded away in the course of the time (it was just drawing
always).
