[#33080] Backup icons - further integration
Contributed by Georg Kronthaler, many thanks!
* enables display of correct file icon on splash screen and in Open Recent menu
* exposes filter_backup in the python api
* enables setting BLENDERFILE_BACKUP as active filter in file browser from wm_operators.c (and from .blend in case this setting will be saved in the future)
* adds a comment to slightly misleading function name file_is_blend_backup()
* Updates icon for backup files to be more consistent with icon for .blend files
rays from the OSL shader. The "shade" parameter is not supported currently, but
attributes can be retrieved from the object that was hit using the
getmessage("trace", ..) function.
As mentioned in the OSL specification, this function can't be used instead of
lighting, the main purpose is to allow shaders to "probe" nearby geometry, for
example to apply a projected texture that can be blocked by geometry, apply
more “wear” to exposed geometry, or make other ambient occlusion-like effects.

Example .blend and render:

Case: multiple scenes, linked objects on different layers.
By definition, a layer is a local scene property - not of object.
On setting scenes, this then gets copied over to objects.
Error was a 2.5 year old commit to allow object layer animation,
which is due to depsgraph issues badly supported anyway.
(animate visibility outliner flags instead)
Fluid sim would stop or crash with node editor.
Bug was a real bad one - the code for giving out WM jobs was messed up for long.
It was giving a running fluid job to the compositer even... tsk!
I will go over jobs code carefully next days to see if it all behaves. Now it
allows per owner multiple jobs, provided it has different job_type set.
Also fixed: preview renders (material) were deadslow once a while - caused
by icon render setting miniature tile render sizes. Now it's fast again,
but there are still 3 icon jobs running per UI change... need to check what.
This feature has been working in OSX for long - to see mouse-overs on buttons
from inactive windows (and tooltips) and allow a button to be active for
input right away.
Will need check by linuxers if this works satisfying. Also Windows now might
support this feature.
Code drawing paint cursors in regions didn't check for zero-sized regions well.
Causing error prints: wmSubWindowScissorSet 0: doesn't exist
Harmless, but nicer to handle it correct :)
KKEY
Previously this would happen silently, so users may not have noticed that these
had been added. Let's see how this goes before seeing if a hotkey change is
needed to prevent even more errors.
This now works for absolute Keying Sets (Builtin Keying Sets are highly context
dependent, and usually cannot be renamed, so this shouldn't be a problem there)
A test variable needed to be absoluted (positive).
Gives expected resuts on negative raiser values.
(next; digging in opencl :)
(In old compo code too, not effective).
Shader nodes (Blender Internal), Math node Power() didn't accept negative
values for input. Added same code as for compositor case - only allow to
raise with integer values for negatives.
That was more like workaround which solved particular issue with freestyle
rendering, but introduced some more uncontrollable issues, main of which is
recursive fracture would likely suffer from non-manifolds results of previous
step.
Boolean operation is not the only way to generate zero-area face, it could
also happen with character animation and it's indeed better be solved from
freestule side.
This should fix: #33041 Boolean difference sometimes produces meshes with holes
