[Soc-2010-dev] Status report for multires

[Nicholas Bishop]

Status report for June 5 - 11:
* Finally have a good base done and committed to build on:
* Committed the stuff I talked about last week
* Modified CCGSubsurf so it can subdivide more than just coordinates
(used currently for masks)
* Modified multires to support updating masks
* Mask layer can be filled, cleared, inverted
* Sculpt brushes now work with masks
* Added a mask brush to sculpt to edit masks
* Wrote some basic release notes:
http://wiki.blender.org/index.php/User:Nicholasbishop/SummerOfCode2010/Release_Notes
* Not related specifically to my gsoc project, fixed various bugs in trunk.

Plans for next week:
* I'm looking now at bringing back the mesh hiding feature from 2.4x
(LMB+Ctrl+Shift).
** This time no ugliness with mesh reordering, I plan for it all to go
through the PBVH and support multires nicely too.
* Plan to look at undo with masks and saving masks.
* If there's time, start working on vpaint.

Schedule:
On track.
