[Soc-2010-dev] Status report for multires

[Nicholas Bishop]

Status report for June 19 - June 25:
* Mask layers committed
* * Works with both regular and multires meshes
* * Works with sculpt undo
* * Has a simple UI

Plans for next week:
* Make masking better
* * First priority is to fix masking bugs that have been reported on the forums
* * More options to control layers, such as layer opacity
* * Then maybe can move on to coord layers

Also, I probably won't be able to make the Sunday meeting this week.
