This commit restores support for freezing or speeding up physics sims. Animate
the "Speed" parameter under Domain->Time, which controls a multiplier factor for
the rate at which the sim proceeds (i.e. the old "Fac-Tim" setting).
Notes:
* Subversion bumped to 4 to patch up defaults for new value so that old sim
files will still run correctly
* Names/descriptions could do with some tweaking
* Porting this across was not that obvious since quite a bit of stuff had
changed (as in, been cleaned up). However, from tests so far, it seems to work
well.
* Some tweaks to the modifier UI
* Hide sharpness property, instead of greying out.
The policy is to use greying out when a property depends on a boolean, if it depends on an enum item, hide it.
=========================
Documentation: http://wiki.blender.org/index.php/User:Psy-Fi/UV_Tools
Major features include:
*16 bit image support in viewport
*Subsurf aware unwrapping
*Smart Stitch(snap/rotate islands, preview, middlepoint/endpoint stitching)
*Seams from islands tool (marks seams and sharp, depending on settings)
*Uv Sculpting(Grab/Pinch/Rotate)
All tools are complete apart from stitching that is considered stable but with an extra edge mode under development(will be in soc-2011-onion-uv-tools).
* Added per surface options "influence scale" and "radius scale" for tweaking brush settings individually for each surface.
* Added option to completely disable drying. This should be nice for indefinitely spreading paint etc.
* Improved paint mixing algorithm.
* "Paint effects" now work in relative mesh space instead of global. This means that effect speed remains same for identical shapes regardless of their size.
* Complete rewrite of "spread effect" algorithm. It now works much better in all test cases done. Old algo sometimes produced artifacts and stopped spreading too early.
* Adjustments / rewrite on some parts of dripping algorithm to make it work better with transparent paint.
* Added a new "color dry" setting. It can be used to define wetness level when paint colors start to shift to surface "background". Lower values can be useful to prevent spreading paint from becoming transparent as it dries, while higher (default) values give better results in general.
* Fix: If multiple displace/wave surfaces were used simultaneously, displace was applied using wrong normal.
Please note that due to these changes in "paint effects" system older save files may require some tweaking to match results from previous versions.
- added back 2.4x 'Vgroup' option to the UI, restricts painting to verts already in the group.
- remove 'All Faces' button in weight paint mode. it doesn't do anything.
Things like brush size and strength accessors now take a scene
parameter rather than guessing about which Scene's unified paint
settings to use.
Setting the size/strength through RNA can now be done separately for
the brush or the UnifiedPaintSettings.
The UI python code required updating to check whether the
size/strength controls should use brush or UnifiedPaintSettings RNA.
Radial control also required some updates to switch between the two
RNA sources.
Added RNA for the unified paint setting flags that matches the Brush
RNA. Fixed the getter/setter functions to avoid guessing which Scene's
UnifiedPaintSetting to use. The getter functions take a Scene pointer
now, the setter functions are removed in favor of a more explicit
approach through RNA:
Rather than RNA choosing whether a property's value is in the Brush or
in the UnifiedPaintSettings, there are now explicit properties for
both. The UI code has been modified accordingly to switch the toggle
buttons between affecting the Brush and the UnifiedPaintSettings.
