This is the core code for it, tools (datatransfer and modifier) will come in next commits).
RNA api is already there, though.
See the code for details, but basically, we define, for each 'smooth fan'
(which is a set of adjacent loops around a same vertex that are smooth, i.e. have a single same normal),
a 'loop normal space' (or lnor space), using auto-computed normal and relevant edges, and store
custom normal as two angular factors inside that space. This allows to have custom normals
'following' deformations of the geometry, and to only save two shorts per loop in new clnor CDLayer.
Normal manipulation (editing, mixing, interpolating, etc.) shall always happen with plain 3D vectors normals,
and be converted back into storage format at the end.
Clnor computation has also been threaded (at least for Mesh case, not for BMesh), since the process can
be rather heavy with high poly meshes.
Also, bumping subversion, and fix mess in 2.70 versioning code.
Main moving logic is moved to new `BKE_keyblock_move()`, which makes it available from anywhere.
In addition, move code was reworked so that it only loops once on whole keyblocks list,
and it accepts arbitrary org and dest indices, not only neighbor ones.
Partly based on work by revzin (Grigory Revzin) in his soc-2014-shapekey GSoC branch, thanks!
So! First, frame for absolute shape keys: never allow a new key to have the same pos as an
existing one (this does not make sense). This way, the two workflows are possible (create
all keys and then animate ctime, or animate ctime and then create keys where you need them).
Also, fixed UIList for shapekeys, the "absolute" test was wrong, and better to show frame
value, even though not editable, than nothing in case of absolute keys.
And finally, add getter to RNA 'frame' readonly value, so that we output real frame values,
and not dummy internal ones (which are /100) in our API.
Notes:
* Did not touch to addons, that's up to the authors. ;)
* Did not removed any "name" field below lists. We might want to do this in some cases (less UI clutter), but probably not always, so will let maintainers of the related areas decide here.
* Give the uiLists a default size of 1, when we don't have any element in it. This saves some space.
Vertex Groups and Shape Keys list will jump to 5 as before when we have an element, due to the additional buttons, for the others, just grow with additional elements.
Notes:
* Made those edits by full checking of py files, so I should have spoted most needed edits, yet it remains quite probable I missed a few ones, we'll fix if/when someone notice it...
* Also made some cleanup "on the road"!
This was caused by r.57812
There were two problems here:
1) vertex_group_vert_select_unlocked_poll() had faulty logic which meant that
it always failed when there were no vgroups present yet - the final return
always just fell through
2) Since the "Assign to New Groups" option was actually implemented using the
same operator as "Assign to Active Group" (just with an extra parameter set), if
the active group was locked, it was not possible to "Assign to New Group" (even
though a new group would not be locked).
Own stupid mistake in recent UI list refactor - those two lists are a good example where a non-void 'id' is necessary, as they use the same class in the same window... Else, the same object is shared by the two, which can't work! :)
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
updating data was only being done on the active object but sticly was being calculated for the selection.
split this into 2 operators, one that works on the selection and another that operates on the active object - so we can have a button in the mesh panels that calculates sticky.
also note that there was no way to calculate sticky from the UI - perhaps this feature should die a quiet death?
anyway - it works better then it used to for now.
currently can remove sticky/mask/skin vertex layers.
regarding the skin layer - while adding and removing the modifier normally works fine, its not 100% reliable since the mesh may be linked into another scene, or be a linked duplicate and the object with the modifier deleted.
Restored single triangle for special menus, which still isn't perfect but
probably makes more sense.
Added drawflag bit flags to button, which is currently used to declare, that
button need to have up/down arrows. This is needed because it's tricky to
distinguish if button should have such arrows. For example, ID search buttons
is a simple block button which doesn't directly mean it'll have pop-up menu
and not all buttons which cases pop-up menu to display need to have such
arrows.
So currently only ID selector button is forcing up/down arrows to be displayed,
all the rest buttons now behaves in the same way as it used to be before.
The up/down triangle icon for menus was not drawing when a menu had
an icon; even though space was reserved there. Note: this can only
work now with removing the ugly "down triangle" icon from buttons like
next to the Material list box (button pops up menu with tools).
Looks nicer this way anyway.
This report points out thet absolute shape keys are unusable.
The problem is there was no way to adjust the play time of a shape key (all absolte shape keys would start at frame zero with no way to change the speed).
Added an 'eval_time' property to the key block that works like the curve path evaluation time, so the time in the keyblock can be controlled.
Realize this is bcon3 but this is was very bad IMHO.
- button adjusting key block was in between 2 object settings - which is misleading/confusing.
- you needed to click through all shapes to check which was muted, currently you's assume 1.0 means the shape is enabled.

Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
