Fixed the other sculpt brushes so they work on multires meshes.

Vertices in the base mesh now get displaced.

Displacements over subdivided edges work correctly now (both for display and updating the highest level.)

Apricot Branch: fix bug with shaders going black.

Apricot Branch: GLSL
====================

* Added initial support for shadow buffers, works in the 3d view and the
game engine, but has known issues still:
* Shadow buffers are made again for each 3d viewport unnecessarily.
* No filtering.
* There was a bug with some shaders going black, but can't reproduce
it anymore?

* Added support for layer lamps, though they're still always computed
in the shader, this needs to be optimized.
* Added support for animating lamp position/rotation in the game engine.

* Fix issue with lamps giving negative light on the backside.
* Fix issue with specular + orthographic camera.
* Fix square spotlights.
* Potential workaround for a bug in the nvidia drivers with shader linking.

Fixed updating displacements for meshes with more than one polygon

length of matrix was incorrect, some scripts may depend on this not sure if we can make the change in trunk.

Fixed updating of normals during sculpting for non-smooth multires meshes.

Enabled updates of normals when sculpting on a multires mesh (only works for smooth meshes now)

Big commit with initial support for sculpting of meshes with the multires modifier.

With this commit, the displacement custom data is being applied to a subdivided version of the base mesh using a modification of CCGSubsurf.

Sculpting on the highest level of the multires mesh now works, with (at least) these caveats:
* Only the plain 'Draw' brush works for now
* Normals aren't being updated during sculpting, so it doesn't actually look right yet
* When displacements are applied or calculated, only interior face points are handled, so original vertices and edge vertices will look wrong after switching levels.

Apricot Branch: issue in last commit with disabling/enabling GLSL
shaders, now it remembers the last one, should be more reliable.

Apricot Branch: Various Fixes
=============================

* Make GLSL shaders work in the game player.
* In the game engine with GLSL and no material assigned, it now falls
back to texface materials. Not in the 3d view yet ..
* Fix memory when using the default material for GLSL.
* Fix another use of the builtin "smooth" name as a variable in the
GLSL code, gives issue on ATI.
* Fix problem with the armature deform being applied to only one
material bucket, gave floating triangles.
* Fix crash when setting .timeOffset through python without a parent.
* Use only gl*ARB functions so that GLSL also works on graphics cards
that do not have opengl 2.0 but do have the extensions.
* Fix use of unitialized variable for render memory usage stats.

Apricot Branch: missed some files in last commit.

Apricot Branch: svn merge -r 15249:HEAD https://svn.blender.org/svnroot/bf-blender/trunk/blender/

(game engine shape keys!)

Apricot Branch: GLSL
====================

* Added GLSL vertex color support in the game engine.
* Added VCol Paint and VCol Light options.

Apricot Branch: GLSL
====================

* GLSL in the game engine now uses the second uv layer too.

Apricot Branch: GLSL
====================

* Added support for the Material and Extended Material nodes.
* Added support for node groups.
* All nodes except Dynamic are now supported.

Apricot Branch: GLSL
====================

* Internal change only: now it compiles the functions separately
once and then links them together with the generated code, instead
of appending the code and compiling them again for each material.
Gives only slight compilation speedup unfortunately.

Apricot Branch: GLSL
====================

* Added support for Ramps, diffuse + specular, all inputs
and blending methods are supported.
