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.

To reduce user confusion, we were already presenting users with an error message
when they tried to edit constraints for bones from the Object Constraints tab.
This commit just makes things more convenient by adding a button which takes
users to the right tab when clicked.
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.
Core issue exists since ages - the thing you get from bpy.types.YOUR_OT_operator is fuzzy, and may change,
due to the fact that both Operator and OperatorProperties share the same name...
Would be cool to get rid of this issue one day, but for now it's safer to use rna acessor...
This commit is to be backported to 2.70.
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!
This re-applied patch from 25cbd13 which was lost at some point
since missing patchset in series.
This revision is to be back-ported to the final 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.
