fix for error in recent commit.

use CMake's OpenMP built in detection rather then defining flags ourselves.

fix [#24810] Mist Settings Are Not Visually Updated When Camera Displays Mist

fix [#24804] filetring of files doesnt work for import/export

bugfix [#24807] nan pixel on Word BG with Angular Map coord texture
also avoid divide by zero with an empty raytree

"Fix" for [#24743] Strand Shading: Distance slider gives different results even when greyed out
* The actual flag was set at render time, was not supposed to be editable manually.

Possible fix for [#23982] Display update with animated nested custom ID properties
* Any property area can have animated properties, so redraw the area on frame changes regardless of the specific property area type.

patch [#24800] Make scene type buttons from material preview optional
from Wenzel Jakob (wenzel)

edit on last commit, for calculating drivers on obdata just check for animdata rather then the object type.
also use switch rather then if checks.

bugfix [#24796] Drivers are ineffective on Text & Curve obj. geometry parameters
also added note that adjusting bone radius changes the parent bone for connected child bones, and fix typo on failing to read startup.blend (both pointed out by MikeS on IRC)

bugfix for pivot constraint.
- no rotation resulted in NAN location.
- subtraction of pivot done in wrong order made the constraint give odd results when rotating on more then 1 axis.

Fixing a crash when dynamically loading a scene that contains a bone parent.

bugfix [#24803] Export UV Layout in PNG (default) corrupts Blendfile

Removing a scene would set the active scene, assuming the scene removed was the current scene. This broke UV Export which used a temp background scene.

[#24802] Invert vertex group not inverting armature modifier influence
the armature vertex group options only apply to Multi-Modifier, rename and edit the UI to make this clear.

use 'const char *' for imbuf and file ops.

remove unused argument.

Bugfix #24795: Typo fix in particle_system.c

Also, fixed indention in armature.c (stupid space-based indention)

Algorithm fix for fluid particles:
* The SPH fluid particle algorithm was implemented a bit wrong. This problem could for example result in the fluid moving sideways after being dropped straight to a horizontal collision surface, a very big no-no as far as real world physics are concerned!
* After some extensive code shuffling the algorithm is now much more true to the paper it was implemented from, and more importantly now the physics should be correct too!
* The main thing was that fluids calculations can effect many particles simultaneously, so just a single loop through all particles can't work properly. As a side note this also means that the actual fluid algorithm can't be made threaded :(
* To make things work I also had to reshuffle some general particle physics code, but there should be no functional changes what so ever to other physics types, so poke me immediately if something strange happens.

Note to users: these changes will most probably effect the way previously done sph fluid simulations look, so some parameter tweaking will be needed to get things back looking the way they were.

Bugfix #22052

OpenGL viewport render gave squeezed results in cases.
Reason: some graphics cards only give offscreen buffers in multiples
of 256 or 512 (my case).

Current fix uses the actual size returned by graphics card, which
is also safe for too large renders.
More elaborate cropping or matching is for another time.

(Added printf for feedback on this, might disappear)

Feature fix

When using Material Nodes, there was no indication in Material
Property window which node was active. The context/channel widget
now shows this.

Better would be to be able to browse nodes in this list, and
to have option to preview only this material (not node tree
result). Enough todo for future :)
