========================
The linear and angular thresholds set the speed limit (in m/s) and rotation limit (in rad/s)
under which a rigid body will go to sleep (stop moving) if it stays below the limits for a
time equal or longer than the deactivation time (sleeping is disabled is deactivation time is
set to 0).
These settings help reducing the processing spent on Physics during the game.
Previously they were only accessible from python but not working because of a bug.
Now the python functions are working and the settings are available in the Physics panel
of the World settings when using the Blender Game render engine.
Python API:
import PhysicsConstraints
PhysicsConstraints.setDeactivationLinearTreshold(float)
PhysicsConstraints.setDeactivationAngularTreshold(float)
OUTLINER_OT_parent_drop
* use scene of child instead of active scene
* poll to check if parent and child are in same scene
OUTLINER_OT_parent_clear
* get scene from child instead of only working on active scene
* poll to check if no parent
OUTLINER_OT_scene_drop && OBJECT_OT_make_links_scene
* memory leak on error
* would only link some objects on error

First node is called Keying Screen (Add -> Matte -> Keying Screen) and it's
aimed to resolve issues with gradients on green screens by producing image
with gradient which is later used as an input for screen color in keying nodes.
This node gets motion tracks from given movie clip and trackign object and uses
them to define color and position of points of gradient: for position marker's
position on current frame is sued, for color average color of pattern area is
used.
Gradient is calculating in the following way:
- On first step voronoi diagram is creating for given tracks.
- On second step triangulation of this diagram happens by connecting sites
to edges which defines area this site belongs to.
- On third step gradient filling of this triangles happens. One of triangle
vertices is colored with average track color, two rest vertoces are colored
with average color between two neighbor sites. Current pixel's color in
triangle is calculating as linear combination of vertices colors and
barycentric coordinates of this pixel.
This node is implemented for both tile and legacy compositor systems.
Second node is basically a combination of several existing nodes to make keying
more straighforward and reduce spagetti mess in the compositor, but it also
ships some fresh approaches calculating matte which seems to be working better
for not actually green screens.
This node supports:
- Chroma preblur
- Dispilling
- Clip white/black
- Dilate/Erode
- Matte post blur
This node doesn't support chroma pre-blur for legacy compositor (yet).
There're still lots of stuff to be improved here, but this nodes night already
be used i think.

This patch also contains some currently unused code from color math module, but
it was used for tests and might be used for tests in the future. Think it's ok
to have it in branch at least.
* Remove all code for Texture and Sequencer plugin system, this never worked in 2.5x / 2.6x and is therefore not needed anymore.
* DNA structures are kept, all read/writefile code is gone.
Parenting was just broken, poll would return true but nothing would happen if you dropped on modifiers or constraints
Parent clear now works the same as dropping on a non-ID_OB types but left the actual modifier/contraint instances open to allow for future expansion
===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.
"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.
See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.
Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.
When in material display mode, mesh_calc_modifiers() calculates the
orco DerivedMesh, which uses a different CustomDataMask. In
particular, it does not necessarily include the current modifier's
requiredDataMask, so those layers might get set to NO_COPY. For the
skin modifier, this resulted in a crash when the modifier internally
copies the DerivedMesh and the output does not contain the expected
MVertSkin layer.
Fixed by adding the requiredDataMask to the orco DM's CustomDataMask.
Also added a debugging function to customdata.c:
customData_mask_layers__print(CustomDataMask mask);
This will print out the names of all the CD layer types in the mask.
