* The input device curves for brush channels
now use a copy on write mechanism.
+ It's based on a global cache of curves.
The alternative is to reference count
BrushChannels, which I also implemented
then abandoned.
+ Profiling showed that copying CurveMapping
instances was actually a problem.
* Lots of small fixes to the old<-> new brush setting
conversion code;
* Brush commands can now, sortof, have individual
spacing. The default brush spacing still acts
as a minimum though.
* Added a BLI_ghash_lookup_p_ex method that
returns the key ptr inside the ghash (it
returns the actual key, not a pointer to
Entry.key).
* Added a general 1d CurveMapping preset operator
that uses an RNA path to get the curve.
