Fix for [#21773] Cast Modifier cant use empties as centers

Based on the assumption that requiring object targets to be OB_EMPTY makes any other object compatible as a target. If the assumption is wrong can be reverted. Only the Cast modifier uses this at the moment and to me it looks like Cast only uses object transform so should be fine.

Fixed incorrect rendering result when bevel object has got modifiers
enabled only for realtime display or only for rendering

Buttons Window Notifier Listener:

* Update several Property Windows for Physic Modifiers in the Physic Tab.
* Update several Property Windows for ND_DRAW Notifier, used by Camera Data, Object Force, and general Object settings.

* Single Column UI for Screw Modifier.

- game engine checking for autoexec was using the wrong global flag.
- 'Trusted Source' option was being overwritten on read making it usless.

Fix vertex paint not getting restored after exiting editmode,
and fix the opposite problem when going to object mode from the menu.
(commit 27747 by Brecht from render25 branch)

Cloth simulation can now use a group to specify which objects
to collide with, in addition to the effectors group.
(commit 27746 by Brecht from render25 branch)

fix rendering another scene from the compositor not working.
(commit 27745 by Brecht from render25 branch)

Optimization for pose channel name lookups using a hash, makes
playback in one particular scene with 3 characters go from 10 to 13 fps.
(commit 27728 by Brecht from render25 branch)

Fix [#21759] Toggle all layers doesn't work

Toggling all layers will revert back to the active layer.

BGE: fix for [#21180] - missing min and max values in the API + mode fix (interval wasn't working)
of course it wasn't only a matter of adding the properties in the api :)

The code of validValueForIntervalProperty and modeChange are the same BUT in the future they shouldn't be, for I think it's fine to keep them as separated functions.

Bonus fix: Also we are now checking if the new mode is interval and update the range expression.

Fix [#20829] "Select Vertex Path" EDGE LENGTH not selecting the proper
vertices (as it did in 2.49b)

Removed popup and fixed code to actually use the operator properties.

Fix [#21745] file that opens in 2.4* crashes 2.5 while trying to open

Only convert old multires data to multires modifier if there are actually subdivisions stored.

Patch by Elia Sarti, thanks!

Fix [#21744] cannot open old file 1 1/2 year old with 2.49 and 2.5 v670

Works around a bizarre situation when an object is it's own parent.
Patch by Elia Sarti, thanks!

#21728: Grease pencil at cursor gives wrong results when the object is not at location 0,0,0.

Removed some code that I never finished working on to try and make the sketches get added relative to the owner. Perhaps will come back to that someday, but maybe we can just do without.

Purging compiler warnings

4 Devs in Agreement - End of the Road for Old Track

This commit removes the Old Track method (used to be found under Object -> Animation -> Track), with all existing instances of this being converted to Track To Constraints. In fact, while performing this removal, I found that this was supposed to have happened in version 2.27 already, but for some reason the options were left in, and this function managed to survive for a further decade.

I've left the tracking axes around still, since it seems some curve tools still use that. However, that usage should probably get faded out in future too?


Misc notes:
* Fixed compiling error with constaints from harkyman's Maintain Volume patch.
* Subversion of 2.52 now bumped up to .2

Fix for ben dansie, incorrect gamma with render baking.
Linear/gamma issues weren't really considered in baking yet.

Bugfix #21757: Crash when setting up cyclic tracking dependencies (with old tracking)

Note that users should not be doing this anyway (and to some degree, I wish that they have to learn this the hard way - i.e. a crash as was before) since it is always bound to cause troubles of various sorts.

Having said this, the old tracking code was previously crashing if this sort of setup was created since a stack overflow would happen while bouncing between each object being recursively recalculated. I've fixed this by commenting out that recursive recalculation (solving the cyclic problems for n >= 2, while n=1 should still be fine without this pre-depsgraph hack), and also removing such cyclic dependencies in the n=2 case.

(PS: Perhaps this is just a good opportunity to just remove this old feature instead ;)
