Some cleanups and optimizations for masks:

* Mesh/grid VBO buffers can now be updated separately for coord/normal data and mask data
* Added a typedef for GPU_Buffers so we don't have the void* cast
* Changed the PBVH update to allow separate updating of mask data
* Fixed a memory leak for the mask_set operator

* fixed crash

* removed duplicate UI and code for texture scaling and center, instead should have used what was already there
* made texture size and offset consistent with how it works in the rest of blender (scaling and offsetting texture coordinates, which is the inverse of intuition)
* renamed 'sculpt direction' to 'sculpt plane' to avoid confusion with another option and make the name more intuitive
* 'rake' is now an icon toggle button next to 'angle', it uses the comb icon used by the particle editor, need a new icon for it
* renamed 'texture offset' to 'texture sample bias' to better reflect its purpose
* controls in the texture panel now go grey instead of disappearing when they aren't relavent
* added several more preset curves, Linear (Maybe conical would be better), Spherical, Root (maybe parabolic is better), and 'Mid9' which is 9 points ready to be customized.
** The icon for Mid9 is a random curve. I think it fits because it is meant to be a starting point to make custom curves, but it may make some people want a random curve feature
** adjusted smooth and sharp curves so they are more continuous (if you have the old one saved you need to hit the button again to get the new one)
* removed Unlimited Clay options from the UI
* In the texture mapping panel (the main one on the right), made offset and size appear regardless of if the panel is in brush or material mode
* Moved 'fast navigate' 'show brush' and 'show brush on surface' to user preferences
* texture sample bias is now applyed before the curve is multiplied. this makes the edges when using a bias much smoother (when using a continuous curve that is)
* made the sculpt stroke mode a proper enum so that the names of the modes appear as strings in the keymap editor instead of as opaque numbers
* decreased crease brush pinch factors hard limit from 2 to 1 to prevent strange behavior
* changed 'show overlay' into an eye icon next to the overlay alpha slider
* smooth, thumb, rotate, and snake hook now ignore the spacing stroke setting
* smooth brush now iterates up to 4 times per dab depending on the strength, so lower levels of strength = more performance
* straighten up the stroke panel, now all controls are show inactive if they are not relavent
* all tools except smooth now use proxies so that they can be combined symmetrically with fewer artifacts, this fixes the bug with the anchor stroke and symmetry
** known bug: for large sized anchor strokes the mesh jitters between two states, this has something to do with proxies and symmetry

* reverting changes to key map, turns out it wasn't a mixup and every sculpting package in the universe uses ctrl=invert and shift=smooth

* made default key map for smooth=LMB+ctrl and invert=LMB+shift

* Moved subsurf grid stuff into it's own header file
* Changed gridkey in CCGSubsurf to not be dynamically allocated
* Fixes at least one small memory leak

minor clean up while looking for why invert isn't working

Implementing Brechts UI recommendations for the texture panel

Render Branch: svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r29819:29826

Render Branch: render layer material overrides can now be restricted
to all objects that are not part of a specified group. Helpful for
creating masks.

* rearranged plane options

== Inverse Autosmooth Pressure ==
* Autosmooth can be enabled to work at low pressure, this can be used to make a "Polish" brush that flattens at high pressure and smooths at low pressure.

* Slider to control how much pinch is applied to crease brush.

* fixed texture angle, it was 90 degrees offsetof

* For some brushes instead of add/subtract the two modes of the brush are named more clearly
* Improvements to the spacing and arrangement of the sculpt ui
* alignment error in UserDef.h (I'm NOT stupid!)
* Adjusted the strength of several brushes when adaptive strength is used, some tools were getting too much attenuation.
* Adjusted the strength of several brushes when used in their inverted modes, some are too strong inverted.

removing pading so it aligns on 32 bit computers too

Didn't mean to recommit strength changes

Sculpt Tool selector wasn't working correctly.

commented out the cylinder test code - it is too buggy to be used right now, left the overlap and other changes.
