Ported joeedh's Euler Filter code from Python to C so that this is
more in line with the other Graph Editor tools - i.e. joeedh's version
only worked on the active bone's curves, while standard tools could
work with multiple bones/objects at the same time.
To use this new version of this operator:
1) Select all the F-Curves for all 3 of the components (XYZ) for the
euler rotations you wish to clean up. In the Graph Editor, they must
be one after the other (i.e. you can't have "RotX, RotY, something
else, RotZ")
2) Activate the operator from the Key menu in the Graph Editor
In an old test file I have floating around, this method did not appear
to be good enough to fix a very clear discontinuity in the middle of
the action, so I'll test some additional methods too
tried doing this smarter by validating the property exists in UI code before access but this ended up making it too complicated and also hard to account for possible access without checking every time.
for now just redraw all areas when a user property is changed.
ui/ --> startup/bl_ui
op/ --> startup/bl_operators
scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
