* Remove support for CUDA Toolkit 4.x, only Toolkit 5.0 and above are supported now.
* Remove support for sm_1x cards (< Fermi) for good. We didn't officially support those cards for a few releases already, now remove some special code that was still there.
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.
* 32 bit GCC builds now have the SSE BVH optimizations turned off, but still
compile with SSE flags for better performance.
* White color when rendering on Windows seems to have been unrelated to SSE,
rather it was a graphics driver not supporting half float textures, added a
check for that now.
* 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.
