dd08305e75 Rename python mathutils functions and split in-place methods from those that return new values.
http://wiki.blender.org/index.php/Dev:2.5/Source/Python/Mathutils
This completes the changes proposed.

This will break scripts (fixing coming up next), for full list of changes see mathutils.c comments.

552b36733b bugfix + minor mathutils.Vector edits.
- multiplying a 2D vector by a 3x3 or 4x4 matrix would use un-initialized memory, now throw an exception.
- use more variable length array BLI_math functions.

c26cc0afa1 bugfix [#25290] Align on text gives a traceback
[#25284] Traceback error on "System Info" script

- Align was only working on mesh objects, now operate on all objects, missing boundbox's are treated as single points.
- obj.bound_box was returning all nan's for object types with no boundbox.
- ENUM_FLAG type enums were showing no text when displayed in operator redo panel.

448d24e7a0 New math util funcitons:
- equals_v2v2
- project_v2_v2v2
- isect_seg_seg_v2_point
which would be necessery for my further multires interpolation commit

M_Geometry_LineIntersect2D now uses isect_seg_seg_v2_point(). Behaviour of this
function was changed a bit -- it haven't returned intersection point in several
cases when two segments are making angle.

a044486d7d [#24267] Hook fails after Solidify
Solidify modifier wasn't assigning origindex values.

- BLI_math.h array functions: range_vni(), mul_vn_fl(), mul_vn_vn_fl(), add_vn_vn(), fill_vni().
- define 'AT' as __FILE__ ":" STRINGIFY(__LINE__), useful for quick debug prints.

7a950c2876 patch from Dan Eicher with some edirts.
vec.rotate(axis, angle)
equivalent to...
  vec[:] = vec * mathutils.Quaternion(axis, angle)

81d5e4f8df bugfix [#22819] Grease Pencil: OpenGL render incorrect if view mode, OK with cursor mode
also made drawing in camera view stick to the camera border (belated durian request),
useful for animation review without worrying about screensize moving the overlay about.

9a85013692 Merge various small changes from render branch:
* Division by zero fix for TNT SVD code.
* Sound fix, in case ffmpeg decode fails, don't use the samples.
* Fix for incorrect bounds of transformed objects in new raytracing code.
* Gave memory arena's a name used for allocations for easier memory
  usage debugging.
* Dupligroup no_draw option was using layers but not restrict view/render
  setting. (not a bugfix exactly but would do display list context switching
  while drawing for no reason).
* Fix objects instanced on hair particles not giving consistent results
  when the object is transformed.
* New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4,
  mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4.
* mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple
  arguments.
* endjob callback for WM jobs system.
* Geometry node uv/color layer now has search list/autocomplete.
* Various small buildsystem tweaks, not strictly needed yet in trunk.

8ec59c7c68 Math Lib:
* inline some more functions, from math_base and math_vector
* also made some changes to the way inline is done so it can
  work for more than one file
* reflect_v3_v3v3 requires input vectors to be normalized now.
* added rgb_to_grayscale
* added zero_v4, copy_v4_v4, swap_v4_v4, is_one_v3
* added box_clip_bounds_m4 to clip a bounding box against a
  projection matrix

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.

bd1f548d8e fix for [#19655] Curve is a disaster
when changing curve twist I assumed 2D curves would not need dir or quat values set, however these are used when getting a path from a curve.
also added interp_v3_v3v3v3v3

* Fix remaining issues before conversion.
* Inline various vector functions, currently enabled for all platforms.
  I expect this to work in GCC/MSVC at least, if other platforms don't
  support it, #ifdef's can be added.
