fde4686d77 barycentric transform utility geometry function.
From 2 triangles and 1 point, the relative position between the point and the first triangle is applied to the second triangle to find the target point.
the barycentric weights are calculated in 2D space with a signed area so values outside the triangle bounds are supported.

wrapped by python:
 pt_to = Geometry.BarycentricTransform(pt_from, t1a, t1b, t1c, t2a, t1b, t1c)

NOTE: 
- moved some barycentric weight functions out of projection painting into the math lib.
- ended up making some of the math functions use const args.
TODO:
- support exceptional cases. zero area tries and similar.

37e4a311b0 Math Lib
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
  conversion script instead, if they use a lot of math functions
  in new code:

f60760e2e2 Python API
Mathutils support for subclassing Vector, Quat, Euler and Matrix types.

Removed C docstrings, prefer to make sure our epydocs are well maintained rather then duplicate, vague doc strings.
Will convert scripts to detect missing docs from the BGE.

d428ba1de8 PyAPI RNA/BGE
* all mathutils types now have optional callbacks
* PyRNA returns mathutils quat and euler types automatically when they have the rotation subtype.
* PyRNA, reuse the BPy_StructRNA PyObject rather name making a new one for each function returned.
* use more arithb.c functions for Mathutils quaternion type (less inline cruft).
* BGE Mathutils integration mostly finished- KX_PyMath now converts to Mathutils types rather then lists.
* make all mathutils types share the same header so they can share a number of functions - dealloc, getWrapped, getOwner.

eb22a7b210 PyRNA API support for matrix types as Mathutils matrix (with callbacks) rather then a generic rna sequence of floats.
Any 3x3 or 4x4 rna matrix will automatically be returned as a Mathutils matrix.
This makes useful stuff like multiplying a vector location by an object matrix possible.
 ob = bpy.data.scenes[0].objects[0]
 print (ob.data.verts[0].co * ob.matrix)

Also added mathutils matrix types to the BGE GameObject.localOrientation, worldOrientation

* MT_Matrix3x3 added getValue3x3 and setValue3x3, assumed a 4x3 float array.
* KX_GameObject.cpp convenience functions NodeSetGlobalOrientation, NodeGetLocalOrientation, NodeGetLocalScaling, NodeGetLocalPosition.
* 2.5 python api now initializes modules BGL, Mathutils and Geometry
* modules py3 PyModuleDef's use PyModuleDef_HEAD_INIT, rather then {}, was making msvc fail to build.
* added macros for Vector_ReadCallback, Vector_WriteCallback etc. to check if the callback pointer is set before calling the function.

bce3f7e019 PyAPI Mathutils Vector callbacks, referencing other PyObjects rather then thin wrapping vectors which is crash prone.
in short, vectors can work as if they are thin wrapped but not crash blender if the original data is removed.

* RNA vector's return Mathutils vector types.
* BGE vectors for GameObject's localPosition, worldPosition, localPosition, localScale, worldScale, localInertia.
* Comment USE_MATHUTILS define to disable returning vectors.

Example...

* 2.49... *
 loc = gameOb.worldPosition
 loc[1] = 0
 gameOb.worldPosition = loc

* With vectors... *
 gameOb.worldPosition[1] = 0


* But this wont crash... *
 loc = gameOb.worldPosition
 gameOb.endObject()
 loc[1] = 0 # will raise an error that the objects removed.

This breaks games which assume return values are lists.

Will add this to eulers, matrix and quaternion types later.

489db9994d Some generic modules from blender 2.4x building with py3k and mostly working.
* Mathutils, Geometry, BGL, Mostly working, some //XXX comments for things to fix with py3

python import override (bpy_internal_import.c) so you can import python internal scripts from the BGE and running blender normally.
