Merging r47307 through r47325 from trunk into soc-2011-tomato

Update startup.blend:

- Added mask sculpt brush
- Draw brush was removed from sculpt mode -- there's SculptDraw brush
- Made default strength for draw brush 1.0 which makes much more sense
especially for weight painting

There's no MASK_OT_select_border in trunk yet

Action Group Colors for Bones (Part 2)

Colors used by Bone Groups are now copied/assigned to Action Groups too when
they're created now. This completes the work started in r.46960 to restore this
functionality from 2.48.

Currently, there is no control over when/whether these colors are copied over
(although it is possible to disable the display of these colors for relevant
animation editors if desired). Originally I was going to make this a more
generic Keying Sets feature, though that turned out to be a bit too complex to
manage.

Other notes:
* Split out the code for copying colors to a common library function

re-remove XOR style writes from inner loop of rasterizer. is pointless and less flexible after blending was added at higher level.

Style cleanup of own recent changes

Added NULL-pointer check to avoid crash in node editor. Fixes #31664

Initial expose of tools into interface for mask editing.
Maybe no ideal, but looks better than completely empty panels.

Reroute nodes, by Jeroen Bakker (patch #28443).

By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when deleting a node, or to control the path of long connections for layout cleanup.

Change in debug print for BKE_mask_spline_ensure_deform -- "alloc new spline" was a bit misleading,
changed with "alloc new deform spline"

Small change to mask slide operator: if current weight goes below zero,
higher weights are still getting affected by weight delta.

Cleanup in spline diffirintiation code - encapsulate max segment length
to resolution calculation functions rather than doing this from callee.

Also switch mask drawing code do the same spline resolution calculation
as used for compositor (which takes frame dimensions into account).

Optimize Gaussian blurs

Style and typo fixes

Changes to mask point slide operator:

- Original slide would create overall feather for spline
- Sliding of feather points for already defined feather would control
individual feather points weight
- Sliding of feather points with Ctrl hold down would switch to
overall feather control

Small refactor of mask sliding operator
Also aspect ratio correction is not needed for BKE_mask_point_set_handle

fix crash in clip graph view (possibly own fault)

Fixed crash
Previous patch allocated temporarily buffers.

Replaced tile based memory manager with a single aligned buffer
- should increase speed with large node setups
- enables caching of buffers in the node editor (in the future)
- OpenCL part still needs some work

Removed unused files in compositor
