add subsurf limits, in RNA, there were none, but subsurf would assert at 29.

Checked and subsurf level 11 gives over 3 million faces from a single triangle. So use this as a limit.

Fix #35082: Blender Freeze when change smoke domain setting

Issue was introduced by svn rev56273 and was caused by
both smokeModifier_do and smokeModifier_reset (which is
called from smokeModifier_do) do mutex lock/unlock.
This lead to quite undefined behavior caused by the same
thread released mutex twice.

Solved by not locking mutex from inside routines calling
from smokeModifier_process -- mutex is locked in parent
function anyway.

Fix a few more cases where an operator should not show in the search menu.

Fix #35080: freestyle Fill Range by Selection operator giving error when invoked
without a linestyle.

Fix #34172: cycles BVH build crashing in some rare circumstances on 32 bit linux.

The problem was (again) the x86 extended precision float register being used for
one float value while the other was rounded to lower precision. This caused the
strictly weak order requirement for std::sort to be broken.

game engine: Use bullet's default contact processing theshold

Blender's old default of 1 was too small here.
Now we don't override the default.
If it's really needed to use a smaller value here, the property should
be first exposed in the ui, but don't think this is necessary.

Fixes [#35076] Dynamic objects have periodic glitch in velocity when on an incline

rigidbody: Code cleanup

Remove outdated comment.

Fix [#34545] Render layer name is unwantedly translated in composite node editor

Some enums' items actually are generated from data (like the render layers of compo nodes), so they should not be translated. Added a PROP_ENUM_NO_TRANSLATE new RNA flag to tag those enums (only found those for nodes, but may be more of them around).

Also fix similar issue in main list of render layers (Py UI code! :P ).

style cleanup

minor fixes for freestyle
- update copying code for linestyles to copy gaps
- update copying code for freestyle line modifiers to copy mapping flags and seeds
- fix drawing code for Material modifiers after a recent refactoring

individual inset was missing relative option.

Fix freestyle crash due to freed memory access. The render data needs to be
freed first, and then the scene that it used.

Fix part of #34640: vertex color blur brush would average face corner colors
at vertices for the entire mesh, which meant that discontinuous face colors
would be lost for unrelated parts of the mesh too. Now only vertices within
the brush radius will be affected.

Fix #35077: cycles incorrectly rendered an empty with dupligroup that was
dupliverted by its parent.

Fix part of #34640: colors darkening when using the vertex paint blur tool.

The problem was that vertex colors only have 8 bits of precision, and integer
division always rounds down, so after some color blending iterations everything
gets darker. Instead use integer division that behaves like round() instead of
floor() for blending operations.

fix:#35073 face normals calculation used wrong mloop index

Fix #35074: Image editor shows color banding on rendered images (even with dither set to 2.0)

Mistake in one of changes to GLSL display function,
missed fallback mode in case dither is non-zero,

ruler tweak: don't, snap to edit-object, because it didnt work well when modifiers are applied in editmode.

ruler snapping
- draw snap circle to make it more obvious when snapping succeeds.
- when not in wire-view, snap to the surface when adding new rulers.

Bugfix [#35075] Physics Panel of Particles Fluid is Truncated

Some RNA Properties were not updated in UI scripts after a recent refactoring
there removing "use_" prefix from some of the boolean properties (strangely
though, while every other property attached to SPHFluidSettings.flag has gone
from "use_factor_blah" to "factor_blah", use_factor_density still keeps the old
prefix).
