RGB curve widget follows user preference DPI now too.

Camera tracking integration
===========================

- itasc adopted for Eigen3 library.
It compiles well, but need deeper testing for regressions.
- Removed Eigen2 library.
- Added settings to tracker which could be changed from UI.
- Pattern area is now affects on tracker.
Currently libmv supports square patterns which are centered
to marker's position. Maximal pattern dimensions is sending
to libmv as pattern size. Would be changed when libmv would
support non-centered and non-square patterns.
- Fixed bug with syncing pattern's flags when tracking.
- Current frame in cache line became a bit more visible.
It's useful for me to when debugging.
- Changed behaviour of "Add Marekr" operator: not it's non-modal
and places marker on mouse position at click.
- Added macro "Add Marekr and Move" which is used to place
markers from toolbar button.
- Added some utility functions to get image buffer under search
and pattern area which also returns relative position of
marker center for this images.
Generated images are more "correct" from coords rounding
POV, but re-calculation of marker position back to
frame coords is more complicated and not implemented yet,
so old not very accurate logic is still used.
- Added preview widget with content of pattern area.

NOTE: files saved in previous versions of this branch could
easily crash on tracking. Use "Reset To Settings" button
from Tracking Settings before tracking selected markers
for such files.

TODO:
- Implement adjusting marker position from marker's
preview widget.
- We've got an idea of sliding marker after click before
releasing mouse button.

Merging r37437 through r37478 from trunk into soc-2011-tomato

Cycles: more work on texturing UI, now texture nodes use same nodes as shading,
only rough implementation for design proposal.

Nodes display now follow 'DPI' user pref too

3D Audio GSoC:
Changed Readers to top-down architecture instead of bottom-up.

Merge with trunk r37475.

fix [#25423] Mirror clipping is ignored with single vertex extrusion when using Face Snapping.

Bugfix: Distance DVar doesn't work with new Local Space

Fixed references in UI to the old property, and adapted the backend
code to work for the new options too.

Bugfix #27573

Sculpt and Paint undo steps kept hanging in the sculpt/paint modes.
Now undo will switch back to global undo, and redo enter the mode
again. Just like weight/vertex paint.

fix [#27659] Segfault when adding None to a group

include some useful info in bge docs, by ZiauddinMK on IRC.

Fixed weird assignment inside condition statement.

revert own fix for [#27648], looks like this needs to work differently to be fixed.

own mistake in recent mask commit.

edit DAG defines to make it easier to add more & modify.

=bmesh=

Removed the DerivedMesh face iterators (they sucked).
This should make subsurf faster. Also sped up multires
a bit (not sure if it's strictly correct, need to look
at it later).

mask modifier: replace bone hash lookup with a boolean array to quickly check selection state.
simple test gives ~28% speedup in building the vertex hash. (no functional change)

mask modifier was taking into account zero weighted verts.

fix [#27648] Weird shading behind grayed out negate checkbox
