/*
The new brush engine is based on command lists. These lists
will eventually be created by a node editor.
Key is the concept of BrushChannels. A brush channel is
a logical parameter with a type, input settings (e.g. pen),
a falloff curve, etc.
Brush channels have a concept of inheritance. There is a
BrushChannelSet (collection of channels) in Sculpt,
in Brush, and in BrushCommand. Inheritence behavior
is controller via BrushChannel->flag.
This should completely replace UnifiedPaintSettings.
