[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [23328] trunk/blender/source/blender/ blenkernel/intern/brush.c: curve could return values lower then zero, making a brush add and subtract the color in different parts.

[Tom M]

Cambo, sculpting also uses this and it is useful to be able to add and
subtract at the same time for mesh sculpting.
