Yep, at last it's here!

There are a few minor issues remaining but development can go on in
master after discussion at blender institute.

For full list of features see:

http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.72/Painting

Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.

0e9084d5ec Fix T39210: Grid Fill is generating mesh that's inconsistent with selected edge loops
Issue was in BLI's rotation_between_vecs_to_quat(), which did not handled correctly cases where both vectors are colinear.

Patch by Campbell Barton and me.

Issue originaly tracked down by Yan Shi, many thanks!

35b61a7512 Move GCC attributes into a centraized defines
Instead of having ifdef __GNUC__ all over the headers
to use special compiler's hints use a special file where
all things like this are concentrated.

Makes code easier to follow and allows to manage special
attributes in more efficient way.

Thanks Campbell for review!

e03b1668e0 code cleanup: remove unused functions
- IsectLLPt2Df

also add attributes for unused function results for some math functions.

82636ab0fb improved method of getting the tangent axis from a bmesh triangle,
rather then getting the longest edge, get the edge which which is most different from the 2 others ends up giving more useful results: for an isosceles triangle it returns the base weather its longer or shorter then the other sides.

1fea6220a2 Woot woot commit.
Stencil style texture mapping. Ready for field testing and user feedback.

This commit adds stencil like brushes, like those that existed on old ptex branch.
(with the exception of clip colour)
To control the position of the stencil, you use

Q: translation
Shift - Q: scaling
Ctrl - Q: rotation

There's extra work that has been done to make this work:

* Support for coloured overlay in vertex/texture painting
* Also made A button do stroke mode selection like in sculpt mode,
when mask painting is inactive.

There are some TODOs to work on during bcon3:

* Support tiled and stencil mode in 2D painting. Support alpha textures also.
* Tidy up overlay code. There's some confusion there due
to the way we use the primary brush texture sometimes for alpha, other times
for colour control.

WIP design docs will be in

69b88cf719 Patch [#33196] Warning Fixes 11-16-2012
* MEM_CacheLimitier - Size type to int conversion, should be safe for now (doing my best Bill Gates 640k impression)
* OpenNL CMakeLists.txt - MSVC and GCC have slightly different ways to remove definitions (DEBUG) without the compiler complaining
* BLI_math inlines - The include guard name and inline option macro name should be different. Suppressed warning about not exporting any symbols from inline math library
* BLI string / utf8 - Fixed some inconsistencies between declarations and definitions
* nodes - node_composite_util is apparently not used unless you enable the legacy compositor, so it should not be compiled in that case.

Leaving out changes to BLI_fileops for now, need to do more testing.

13254cde8c Alternate mask spline feather offset calculation method: now there are 2 [Even | Smooth]
- Even preserves thickness but can give unsightly loops
- Smooth gives nicer shape but can give unsightly feather/spline mismatch for 'S' shapes created by beziers.

This is an example where smooth works much nicer.
