fix for possible comparison of un-initialized variable.
vol_get_bounds() only runs when shi->flippednor==0, but is.hit.ob was being checked afterwards irrespective.

bugfix [#25459] Zooming out with view3d.zoom() crashes blender completely

Constraints UI Tweak:

Experimental tweak for the "Object Constraints" tab so that it now
shows a warning message instead of the "Add Constraints" button when
the active object is in Pose Mode. Hopefully this will further
alleviate any confusion over Object vs Bone level constraints.

Todo:
While coding this, I noticed that we currently don't have any way of
making help-text labels in UI panels which can span multiple lines
(word-wrapped or manually split). Probably not a critical issue, but
it would be nice for completeness...

"Red-Alert" flags can now be set on UI layouts via the RNA API too

Bugfix:

Setting the group for F-Curves from the Py-API (i.e. to move F-Curves
from one group to another) was failing. After debugging this, this
functionality should now work correctly, while still prohibiting the
setting of groups on "F-Curves that aren't in actions" (i.e. driver-
fcurves)...

Fix #25456: using Live Unwrap always unwraps with method Angle Based.

Bugfix #25446 (and todo item)

The icons for materials were always lagging or not updating
at all. I also found it suspicious slow...
It appeared that the icons now store a "mip level", where for
every change in Materials 2 render jobs for icons were started,
one for 32x32 pix, one for 96x96. The latter was cancelling out
the first job almost always.

Also made preview renders detect size, to set amount of tiles
to be rendered. Small icons use 1 part, larger previews 16 now.

All in all, behaves much smoother now! But, will also update
the thread Jobs manager to allow "delayed jobs" like for icons,
these are aggressively put as first in the jobs list.

Spelling fix: itterator->iterator

Merged changes in the trunk up to revision 34010.

Small changes to new pointcache code:
* Removed the unused fuctions spotted by Campbel.
* Removed the gotos to make Ton happy.
* Added better debug prints to disk cache operations.
* Fixed a memory unmap error that seemed to happen on a test file.

Splitting quad into triangles and merging triangles into quad should
work correct with sculpting data now.

Joining two triangles could give incorrect sculpting result for
special topologies, but it's that case that can't be nicely handled
with our layers architecture.

New customdata layer callback: validate
Used to validate displacement allocation size after face copying
to match face vertex and displacement corners count.

Multires math function used for layer interpolation moved from customdata.c to multires.c

No functional changes

Crash fix for pointcache... bad goto's here.

Small feature for debugging pleasure:

The svn revision nr is saved in Blender file header now.
Can only be retrieved with running blender -d now.

Bugfix 25451

Tooltip for "default render output" was wrong.

- correct typos in comments.
- move boxpack struct out of the public header.

Fix #25435: remove code that enabled EWA filter on mipmap toggle, should not
have been there, mistake in removing SAT filter.

CMake fix so MSVC works again. Fix suggested by Tamito Kajiyama.

Quiet warnings from last commit.

Janne: could you check if ptcache_file_pointers_seek() & ptcache_read_init() can be removed?
