This is a WIP to allow 'unified brush settings' ie when you change strength or size of a brush it updates for all brushes. Also in this commit are stubs.c changes needed for gameengine compiling

Adding in sane multiplier values and having DEEPEN, PEAKS, and CONTRAST (invert of FILL, SCRAPE, FLATTEN) with a lower multiplier. These should give much better brush behaviour out of the box

* Beginnings of using preview and icons to select brushes.

* Collapsed the tool selection into a listbox so that it becomes less of a tempting target to mess up your brush presets.

* Alt-key smooth and Shift-key invert are now properly done as modifiers to LMB sculpting. This means they can be remapped to other buttons (for example, putting "Alt-smooth" on the RMB or whatever).

** Serious downside is that it is now not possible to do invert or smoothing in the same stroke. You have to let the mouse button go and start a new stroke to change the mode.

** Minor downside is that the cursor no longer changes when you change the mode of the stroke by pressing the key.

I believe these downsides will be resolved and that the benefit of having a proper re-mappable operation outweighs the downsides.

* Cleaned up the properties that appear in the key map configuration for LMB, LMB-Shift, and LMB-Alt. Only "ignore background click" was actually supposed to be there.

* I quieted the warnings generated by paint_image.c and in the process found an error where a result was supposed to be rounded to the nearest integer but instead was always truncated.

* I quieted a warning about signed/unsigned mismatch, it may have been better to actually fix that one.

Render Branch: volumes with the camera inside were rendering on all
render layers even if the object was on a different layer.

Render Branch: better error message when failing to read displacements.

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r29653:29687

== Alt-Smooth ==
Press alt-key to switch to the brush preset named "Smooth" (it may or may not smooth depending on if you messed up your preset /sigh)

* syntax error in shaders caused by lack of a newline

*Flatten/Contrast brush was not showing the "Add/Subtract" control in the UI.
* Deleting shader programs only requires ARB_shader_objects
* Slight speedup on the smooth brush

Added undo pushes for the mask_set operator. Also removed a bunch of old crufty declarations in sculpt_intern.h.

Enabled multiple paint mask layers for both regular and multires meshes.

* Iteration over vertices in the PBVH now has two mask components, the active mask, which is editable by the mask brush, and the combined mask, which adds all the mask layers together (clamped to [0,1]), and is used to mask off other brushes
* Layer adds and removes are handled by the paint undo system used in sculpt mode
* Added a new customdata function that adds a layer at an offset (into other layers of its type.)

Render Branch: move tile cache init a bit earlier to fix baking crash.

Render Branch: baking stability tweak, set G.rendering during bake to
disable drawing in 3d view, etc, same as for regular rendering.

Render Branch: attempt to fix crashes with tile cache + baking.

Render baking bugfix (applies to renderbranch only)
lightgrouphash wasnt initialized

Render Branch (only) workaround for
[#22662] Transforming handles in the graph editor is broken.
