Fix #22553: dragging number buttons would run update functions more often than
necessary due to the more accurate mouse move events that are useful for
sculpting and painting (at least on Linux/X11, not sure about other platforms).
If the update function takes a while to run, this in turn causes more mouse
move events to be accumulated, making things even slower, .. going into a spiral
of slower and slower redraws.

As a solution I've added a INBETWEEN_MOUSEMOVE event next to MOUSEMOVE. A
MOUSEMOVE event is automatically changed to INBETWEEN_MOUSEMOVE when a
MOUSEMOVE event is added after it. This new event type is only handled by
painting/sculpting operators, everything else can happily ignore it.

Compile fix for changes in "filldisplist" function.

Fix #21370: VBO does not display material colors in textured solid.

- avoid divide by zero with node progress
- write_crash_blend() was writing to the original path.

Fix #21369: normals on extruded text and curve objects were flipped
for the backside, giving problems with e.g. boolean operations.

Fix crash when rendering with output to full screen and the mouse
cursor not over any area, e.g. on the border between two areas.

Sculpt+shape keys:
- Sculpting on the basis key should change original mesh
- For relative keys sculpting on basis key should update others

fix for rare crash when a material is set in the outliner for an object with no material bits.

Fix a crash when failing to read .tga files in some cases.

Converting a mesh into a mesh (alt-c), was broken with shape keys and modifiers that changed the vertex count.
removal of the shape key was undone in DM_to_mesh().

Fix #21470: changing brush settings redraws the 3d view unecessarily,
added ED_region_tag_redraw_overlay to only redo overlay drawing, which
in case of triple buffer is much faster.

Fix #22654: Converted curve from mesh disappearing

Curve object should have ob->bb=NULL if there is no derivedMesh

fix for timeline drawing with new cache visualization.
memcpy buffer overrun when the first frame wasnt 0.

Logic UI: small change: make pin always visible (disable sometimes instead of hiding)
I still think we could use a more compact header for the non-expanded mode (ala 2.49). To be addressed later

Change to file output compositor node -
Now it only outputs files when rendering, otherwise, it overwrites the output files
whenever the compositor updates (i.e. just scrubbing through the timeline )

Added back full scene motion blur 'shutter' parameter (was 'Bf' in 2.49)

mathutils.RotationMatrix

Angles are in radians. Doc and example should reflect reality

Small update to text boxes UI. It now works in single-column layout.

Fix #22642: NURBS surfaces doesnt display
Fix #22587: Invisible Nurbs Suface

There was a small bug with determinating if new object should be created
and for surfeces new OB_CURVE object had been created (instead of OB_SURF).

Removed unused function and enum, which were used by nurbs surface
create old oprator

== Sequencer ==

Removed "frame_locked"-flag from sequencer completely, since it doesn't
work any more in Blender 2.5. (All IPOs are frame-locked now anyways.)
