Fix for bug #6753: metaballs instanced by a particle system did not
refresh properly, also fixed a memory leak.

Fix for bug #5862: crash rendering to quicktime h.264. This would need
an upgrade to the new quicktime api to work, but that's not really
compatible with rendering out frames sequentially. For now it sets the
compression to minimum quality, which doesn't need seeking forward and
backwards.

Fix for bug #8932: crash converting old particle system.

Fix for bug #8930: issue removing temporary pointcache directory on windows.

simple fix for "Unable to make version backup" warning when saving files. missing a return.

For *nix sustems, recent physics pointcache refactor uses stdio.h's remove() rather then system("rm -f ...") for removing files, since it was a lot slower for removing pointcache.

Ton used the system command because there was some problem using remove() ~6years back, but he cant remember why, (maybe its not a problem now)

Simple error, remove wasn't returning a value, but keep an eye out for problems removing files, and if anyone can reproduce the "Unable to make version backup" problem when saving, we should look into it.

Also added a note about using # in the output path for blenders command line help text.

fix BGE patch #7892: dRot motion is reversed on non-dynamic objects

Positive dRot motion actuator will now make the dynamic and non-dynamic objects rotate counter-clock wise.

Moved initialization of vertex flags up a bit in the subdivide
routine because they were trumping a fix I had made earlier
to deal with subdivide smooth and mirror modifiers.

Campbell, could you please check that this commit is compatible
with the results you were expecting from commit 14227? Here
is the log of that commit:

This is patch [#8531] Change gamma node max value

Submitted By:
Stephane SOPPERA (soppera)

It just increases the max value for gamma correction to 10f. Which
as noted in the patch is the same as the Gimp's color level tool.

Changed BLI_convertstringcode to replace any number of hashes with the frame number.

somefile_##.png -> somefile_01.png
somefile_########-image.png -> somefile_00000001-image.png

Before, A hash at the end of the string would be replaced by a number with 4 characters. This is still default if no #'s are in the string, so nothing has changed.

To use this function from the python api use scene.render.getFrameFilename()

Fix for bug #8920: particles reactor crash and memory leak.

Constraints-UI:

* Fixed typo in tooltip for IK Constraint
* Beautified Limit Distance constraint a little bit

Little cloth code cleanup needed because of from new cache code merge

Partial commit of patch #8812 (fixing inlining on sunOS)

Fix for mistake in pointcache refactor commit.

Fix for bug #8898: QMC AO not working correct on objects pointing
directly at the camera in some cases.

Point Cache Refactoring
=======================

Caching and Baking:
- The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates.
- There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles.
- The cloth autoprotect feature was removed.
- The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries.
- The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions.
- PointCache struct was added to DNA and is automatically allocated for each physics type.
- Soft body now supports Bake Editing just like cloth.
- Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now.

Library Linking:
- Added some more warnings to prevent editing settings on library linked objects.
- Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked.
- Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh).

Physics UI:
- Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth.
- Tweaked field panel buttons to not jump around when changing options.
- Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable.
- I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers.
- Fixed modifier error drawing glitch.

Particles:
- Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() ..
- Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading.
- Make particle threads work with autothreads.

Continue Physics:
- The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache.
- This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics.

Todo:
- Point cache can get out of sync with and undo and changing a file without saving it.
- Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion.
- Menu item and/or buttons for Ctrl+B.
- A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested.
- The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.

Fix for render scemode in the python api, forgot to commit this file
when i changed it from a short to an int.
