support for string parameters in OSL nodes
for now subtype is not defined, but once we start parsing the metadata we can set texture inputs as FILEPATH
also, it takes relative strings and convert to absolute for all strings (which is arguably a good solution, but
should work for now)

Fix cycles crash with normal map node, issue with tangent sign attribute.

Cycles: tangent and normal map now show UV map link menu instead of text field.

[#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

Fix for previous commit, didn't compile on windows.

Cycles OSL: support for the trace(point pos, vector dir, ...) function, to trace
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.

Cycles OSL: phong_ramp(N, exponent, colors[8]) closure added, which works like
a specular ramp shader. Note this is OSL only still, for experimenting.

Patch by Thomas.

Cycles: 4 new nodes.

* Tangent: generate a tangent direction for anisotropic shading. Can be either
radial around X/Y/Z axis, or from a UV map. The default tangent for the
anisotropic BSDF and geometry node is now always radial Z, for UV tangent use
this node now.

* Normal Map: generate a perturbed normal from an RGB normal map image. This
is usually chained with an Image Texture node in the color input, to specify
the normal map image. For tangent space normal maps, the UV coordinates for
the image must match, and the image texture should be set to Non-Color mode
to give correct results.

* Refraction BSDF: for best results this node should be considered as a building
block and not be used on its own, but rather mixed with a glossy node using a
fresnel type factor. Otherwise it will give quite dark results at the edges for
glossy refraction.

* Ambient Occlusion: controls the amount of AO a surface receives, rather than
having just a global factor in the world. Note that this outputs a shader and
not a color, that's for another time.

Cycles: disable OpenCL in builds for now, since it's not working and is only
confusing users at this point. For experiments you can define the
CYCLES_OPENCL_TEST environment variable to make it show up in the UI.

Fixes related to #33087:

* Fix GLSL memory leak in the (vector) math node.
* Fix GLSL math node pow behavior for negative values, same as was done for C.

quick hack to allow 10.8 to build again, will wait Jens for real fix
but basically the error I get is:
Error: redefinition of enumerator 'NSEventTypeRotate'
...

for all the NSEvents

Bugfix #32191

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)

Fix using uninitialized color pace name in IMB_testiffname

Bugfix #33092

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.

OSX: substitute all MAC_OS_X_VERSION defines with MAC_OS_X_VERSION_MIN_REQUIRED macros, to get more reliable version (api) covering

was trying to make py import follow pythons own code more but broke py32 compat. this should fix

Bugfix: on Linux (X11) the inactive window was not getting mouse-move events.

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.

Release environment script: make python linking to openssl statically

fix for imp.reload() with Python3.3, function was recursively calling its self.

Bugfix #33096

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 :)
