* OSL rendered Black with Compatible Fallof option, fixed.
Note: OSL uses compatible scattering when "Compatible" or "Bicubic" is selected. I guess compatible will be removed later? If not we need to fix this properly.
* fill-holes operator now takes advantage of new edge-net fill, works in many more cases then it did before.
* face-create that uses edge-net now initializes the normals based on surrounding geometry, only running normal calculation if there are no connected faces for a reference.
New features:
* Bump mapping now works with SSS
* Texture Blur factor for SSS, see the documentation for details:

Work in progress for feedback:
Initial implementation of the "BSSRDF Importance Sampling" paper, which uses
a different importance sampling method. It gives better quality results in
many ways, with the availability of both Cubic and Gaussian falloff functions,
but also tends to be more noisy when using the progressive integrator and does
not give great results with some geometry. It works quite well for the
non-progressive integrator and is often less noisy there.
This code may still change a lot, so unless you're testing it may be best to
stick to the Compatible falloff function.
Skin test render and file that takes advantage of the gaussian falloff:

- Removed the cycles subdivision and interpolation of hairkeys.
- Removed the parent settings.
- Removed all of the advanced settings and presets.
- This simplifies the UI to a few settings for the primitive type and a shape mode.
- optimize BM_face_exists_overlap_subset(), dont check faces smaller then the vert array, don't initialize overlap flag unless its needed.
- BM_face_exists_overlap had incorrect check (currently function is unused so no harm done)
This is done by fixing logic for finding the first unused element in treehash.
The blend file from [36486] also exposes a memleak, but it should be addressed separately.
Any GLSL materials loaded after lights are LibLoaded will now use the lights in
heir shaders. This includes materials loaded from the same scene as the LibLoaded
lights. We could later add a new flag to LibLoad to recompile all existing shaders,
but this commit should offer a lot more flexibility as is.
This will make transitions from older versions of Blender easier since VSYNC_ON
will be the default. This could have been changed in a do_version, but the vsync
code has yet to see an official release, so I figured this would be a bit nicer.
Also, this makes VSYNC_ON the default for new scenes as well.
previous code created faces with mixed face-flipping and could get very slow,
test with ~60,000 edges here hung my system for over 2min (didnt wait for it to finish), new code executes in about 1 second.
new code doesn't attempt to flip faces correctly, its quite involved to do so, especially when the new faces are not created adjacent to eachother.
so simpler to calculate normals afterwards.
This disables crazy adaptive sampling happening in diagonal direction.
This still gives some doggyness, but it's much less dramatic now,
and behavior is pretty damn the same as EWA filtering when rendering
textures with Blender Internal.
Problem is that the read/write buffer operations only work with actual
image inputs. If a singular value is used as group input no actual
buffer will be created, the write operation does not schedule any chunks
and the ReadBufferOperation subsequently returns zero
(MemoryBuffer::read).
The fix uses the (0,0) resolution to detect single value input of the
WriteBufferOperation. The actual resolution is then clamped to (1,1) to
ensure we have a single pixel to store the value in. A m_single_value
flag is also set, so we can reliably distinguish this from genuine image
resolutions without having to check m_width/m_height later on.
The ReadBufferOperation copies this flag from the associated
WriteBufferOperation and if set will always return the single value from
pixel (0,0).
the subset version of the function checks if any faces has all its verts in the given array.
also made some additions to linklist functions (arena and pool versions of append).
In fact, there's no need to get float buffer at all,
conversion could be done in pixel processor level
after interpolation.
It might give slightly worse interpolation results
(which i'm not sure would be visible by eye) but
it gives more than 2x speedup on my laptop on node
setups used for warping image.
