This glsl shader works for OCIO with alpha. OSX iMac with ATI.

There's no logical reason I can find... but I commit it because many others have
the same error, so we can check.

Bug fix #35117

Sequencer: Properties region didn't have the general Sequencer keymap, so it didn't
respond to "Nkey" to hide the region.

Bug fix #35124

Outliner was drawing "Animation" category even when no actions/strips/drivers existed.
Would happen after adding Action and unlinking it.

BGE: Fix for [#34383] Blender crash Steering actuator 2.66 -> 2.59 -> 2.66. Reported and fixed by HG1.

fix for crash while drawing editmesh with weights in rare cases when the length was set but array NULL.

fix for out of bounds memory read when running wire-frame tool on empty mesh.

minor changes, BLI_uvproject_from_view was doing matrix multiply for no reason, quiet float/double warning.

BLI_strlen_utf8 was doing size_t / int conversion unnecessarily.

remove unused function: projectf

add vertex color smooth operator.

Since the bug was fixed that made blur brush _not_ blur all verts, there is no way to blur vertex colors after baking.
While this was hidden it was useful especially for baking vertex colors.

Solve possible uninitialized variables usage in sequencer draw function

Fix for fix in alpha de-premul

We do not need to premul shader result, opengl
is already configured for straight alpha.

quiet warning, color blend c file was missing own include, also minor style tweaks.

Premultiplication in OCIO shader went wrong,
it used to apply alpha on source color after
conversion, not on result.

Apparently better not to use values like 1.0f in GLSL code

Fix from debug session of self and Ton, was affecting OSX
builds, making GLSL display transform not working on this
platform.

Print error log to the console if OCIO shader compilation failed

Some color space issues in sequencer:

Sequencer was always trying to do GLSL color space
conversion, not respecting user settings at all.

This failed a lot when RGB curves a used in color
management settings.

Now sequencer will fallback if GLSL can not be used
and will also respect user settings (however, draw
pixels are not supported, sequencer always uses 2D
textures).

"Bug" & usability fix, own collection.

Color Pickers in Blender support precision editing with holding Shift key.
Unfortunately, on first click the picker cursor moves to the mouse position,
making the precision dragging quite useless.

Now, if you hold Shift, the picker editing will only apply the delta motion
of your mouse drags, making it much nicer for fine tuning of color grades
in Sequencer or Compositor.

Fix #35113: solidify modifier not preserving clamp option on duplicating the
object or modifier.

Fix part of #34233: bad alpha blending for 2D image painting. This is a very
old issue, the formulas here were never quite right, should all work ok now
with byte and float images.

Some differences:

* Colors with zero alpha from the background will never have an influence, so
you don't get alpha fringes when painting over such areas. This does give
hard edges when looking at the RGB channels alone, but there's no way to
avoid that and fringes at the same time, same behavior as other painting apps.

* Add/Subtract/Multiply/Lighten/Darken now leave the alpha channel unchanged
and work only the RGB channels, again same behavior as many other apps.

* Erase/Add alpha now compensates for premultiplied float images to keep the
straight RGB colors the same.

Next: fix projection painting.
