[Bf-committers] BMesh undo proposal

[Nicholas Bishop]

Hi,

I'm looking into implementing undo/redo for BMesh that doesn't require
making a full copy of the mesh each time. I'm interested in this for
dynamic-topology sculpting, but it should be useful for regular Edit
Mode too.

I've got some minimal code and a wiki doc describing it here:
http://wiki.blender.org/index.php/User:Nicholasbishop/BMeshUndo
https://github.com/nicholasbishop/blender/commits/bmesh-undo

The code is quite incomplete still, but works for simple cases. I'd be
interested to hear any thoughts or potential issues...

Thanks,
-Nicholas
