Issue was in BLI's rotation_between_vecs_to_quat(), which did not handled correctly cases where both vectors are colinear.
Patch by Campbell Barton and me.
Issue originaly tracked down by Yan Shi, many thanks!
This is a regression caused by rB67134a7bf689279785e2e40b29cd24243813998b
The UV coordinates read from the UV input must be scaled by the Image
input size instead of the UV input size.
Also now this node uses the UV input resolution instead of the Image
resolution, since this is what determines the available resolution. The
image is EWA-sampled anyway, it's resolution does not have a direct
impact.
This provides a speedup to evaluating long F-Curves in fcurve_eval_keyframes()
by using the pre-existing binarysearch_bezt_index() function (used for keyframe
insertion) to find the relevant BezTriple on the FCurve at the current evaltime.
The current code loops over all BezTriples (sometimes not even breaking from the
loop after cvalue has been evaluated).
Reviewer Notes:
- Unlike in the original patch, we use the old/existing logic instead of
checking that (exact == true). See comments in code and also on the tracker
entry for this patch for more details.

This is a failure of viewport direct displist creation
caused by existing curve_cache pointer which empty content.
Made it so if the curve isn't evaluated it's curve_cache is NULL.
This is just-another-regression to be ported to the release.
Basic idea is to check whether an element is visible or not, and ignore those that are hidden, during move up/down.

Fluid particles use the particle system's bvhtree structure, which is a
runtime BVH tree. This was not reset properly on copying objects/psys,
which lead to concurrent access in threaded depsgraph updates and memory
corruption.
This is mostly useful for precision in lift/gamma/gain nodes. Display of
those values is done with linear interpolation while saturation is
interpolated cubically. This will lead to color inconsistency between
selected and displayed color on color pickers for instance, which should
be avoided on those use cases.
This was supposed to fix inaccuracies between S-H wheel but it makes the
colors selected through the SV-H color cube wrong (see http://
%28SV-H%29-Inaccurate). Instead of deactivating color management for SV
and H widgets just reenable correction for the Hue wheel. This is wrong
because HSV always refers to display space and we -have- to account for
that when using linear color RNA properties.
history operator (Ctrl + Alt + Z).
This will only show paint operations now while in an image paint mode.
The caveat is that user can delete previous paint operations too (even
on images not on the canvas currently) so it needs some care. This is
consistent with regular undo behaviour though.
Sculpting also suffers from lack of Undo history support, this will be
added in a separate commit.
We can't simply dupalloc cache_system (LaplacianSystem), it has quite a few allocated data we'd need to dupalloc as well,
not to mention (nl) context... Much safer to just set it to NULL in new copy imho!
This commit is to be backported to 2.70 release!
Own regression since partial buffer update refactor,
display buffer for exr tiles should happen in image
update callback.
This revision is to be merged to the final release.
The previous fix 162d6c73e3 has been cancelled because it caused a
problem that mesh deform cages and so on mess up the preview. To avoid
the problem, viewport doesn't show mesh object if its draw type is
bounding box or wireframe.

This is a standard Hue - Saturation - Lightness model
(see for instance entry on wikipedia here: https://en.wikipedia.org/wiki/HSL_and_HSV)
Note though the difference between HSV and HSL saturation, which are not the same.
The advantage of having this color selection scheme is that artists can select
shades and tints of a color easily by using the lightness slider. Also colors
are arranged on (approximated) perceived lightness on the color wheel.
Beware, Old files opened with this preference saved will crash!

Enum icon-only buttons were getting their strings set,
then truncated with blenders string shortening methods, then not drawn
because there was no room (since buttons are icon width).
Modify UI code so icon-only buttons don't get names and passing "" to a
button won't have its text set later on.
This is a regression introduced in fbc7ab30f and caused by the wrong object
being passed to the function.
Not sure passing editnurb as an argument is a good thing to do..
