[Bf-committers] patch 19239: branches/bmesh/blender face selection similar face selection

[Wael EL ORAIBY]

That's a great news, :) I ll try to work on similar area selection
now. For textured faces, I need to do more tests, blender seems to
crash when I load a textured + material texture object (a blender
2.49a file). Since, the unwrap UV is not working yet :-/ , we might
need to discuss this further. I ll keep you informed.

Wael,
