We now support the combined layer of Photoshop files (stored as layer 0
in the file). This way users can keep their files as multilayer PSD and
Blender always handle them as flat images.
For perfect alpha this requires an OpenImageIO update:

Photoshop sample files:

Brecht has some pending fixes to push for OIIO as well, so we may as
well wait to update our libraries.
What works:
===========
* 8bit images (with or without alpha)
* 16bits images (alpha discarded)
* Photoshop files saved with 'Maximum Compatibility'
* Cycles, Blender internal, BGE (and player)
Known limitations
(due to OIIO dependency):
=========================
* Images with less than 4 channels show a wrong thumbnail (bug may be in OIIO)
* Packed images are not supported
* We do not write PSD files.
Note: old Blenders have support for PSD via Quicktime library. But due
to license issues this was discontinued.
Many thanks for Brecht van Lommel for reviewing the patch, suggesting
multiple improvements and to help solving the alpha issue.
The ear loop method is potentially too slow (OˆN).
We are not using the 'beauty' option at the moment.
I'll incorporate that next.
(and later specific methods for quad splitting)
Patch done in collaboration (and reviewed by) with Campbell Barton.
* Remove the compatible falloff SSS implementation. We shouldn't support two implementations in the long term, and 2.7x is a good release number do break some compatibility as well.
* Version patch added, so Files with Compatible falloff will automatically use Cubic now.
It was already mentioned in the manual, that Compatible is deprecated.

The SAMPLELINE flag in histogram was set during the BKE_histogram_update_sample_line function. That function in turn is called during every scope update in area draw function, meaning that during render
it constantly gets set. OTOH the operator tries to disable the flag on invoke, which "cancels" the sample line by default. So during render the operator un-setting of the flag has no effect, because the
render job immediatly triggers a redraw, which updates scopes and sets it again.
Moved the flag out of the actual sample line update function into the operator execute. Now only the operator enables/disables overall sample line drawing, while the rest of the update works as before.
HSV values were calculated from a linear space color, which is
not so much useful and correct. Now RGB(A) buffers will use
color managed color for HSV values.
Still not sure which color to use for HSV when there's only one
channel in a buffer. This part left unchanged for now.
and restore of window setups with multiple monitors, but they are also causing
regressions, in particular issues with Blender overlapping the taskbar and the
user preferences opening wrong. We decided to revert to the old behavior for
the release.
See bug #36707 for the full explanation.
* The mask was not subdivided properly on splitting edges, which gave interesting
but definitely wrong fractal-like borders around masks.
* Edge splitting was only done where the mask was < 50%, with the reasoning that
you can't do a 50% topology update. But this gives an ugly border in the mesh.
The mask should already make the brush move the vertices only 50%, which means
that topology updates will also happen less frequent, that should be enough.
to quickly toggle it on/off.
Problem is accessing freed data, now the job is ended immediately. Fix based
on patch from Sergey and investigation from Bastien.
Scene/Render "spaces" are actually absolute values, they do not use the input X/Y scale factors, hide them in this case.
Thanks to Lukas for review and improvement!
