The option has always (un)set the "Overwrite" flag on all strips. Calling
it "Override" seems misleading, since even when unchecking it, it overrides
whatever was set on the selected strips. It really just (un)sets the
"Overwrite" flag, and now it is also labeled as such.
In the reported example it seemed reasonable to apply this change.
But it causes a much more common case (selecting projections)
to be split into 2x islands.

This makes sense when we want to avoid float precision error
for near co-linear edges. OTOH, this is an arbitrary decision,
so keep functions separate.
That problem occurs because of the imprecision of `short int` (16 bits).
The 3d coordinates are converted to 2d, and when they are off the screen, their values can exceed 32767! (max short int value)
One quick solution is to use float instead of short
The snap code is actually a little tricky. I want to make some arithmetic simplifications in it
The only similarity between these functions is that both serve to snap.
However their codes are totally different from one another.
So by separating these functions, it:
- removes the need to put several conditions;
- simplifies and
- optimizes the code
* Display a warning above the pose list if the pose library is in an invalid
state (i.e. when it has keyframes but no pose-markers associated with those
keyframes). This warning prompts users to run the "Sanitize Pose Library Action"
operator, which should fix up such issues.
* "Sanitize" operator now creates unique names for each newly create pose
marker it generates, including the frame on which it found the pose
The problem here was that the "frame_start" and "frame_end" RNA properties of
the Stepped FModifier were shadowing/overriding "frame_start" and "frame_end"
properties of the base FModifier. As a result, when the range() callback
for the In/Out parameters (defined as part of the base FModifier) checked
it's start/end properties, they were always still zero, meaning that the
acceptable range for the In/Out parameters was 0 -> 0 = 0.
Note:
If you've got old files with this problem, you'll need to manually click on
the frame_start/end properties to flush out the old values. It's probably
not worth the effort of applying a version patch for this (given that this
modifier is not one of the most often used ones AFAIK).
As with Strip Time, the updates here would get triggered before the
autokeying had a chance to record the unkeyed values, making it impossible
to autokey.
The issue was caused by combination of following factors:
- Clipboard cleanup function will pass node tree as NULL to node free
function.
This is fine on it's own, we don't have tree in clipboard.
- Node free function will call node storage cleanup only when there is
a non-NULL node tree.
This is somewhat weird, because storage cleanup does not take node
tree as argument.
So the solution here: move node storage cleanup outside of check that
node tree is not NULL.
imapaint's clone and canvas are refcounting Image usages.
And particle's editsettings' object and scene seem to be pure runtime
data (they are reset to NULL in readcode), so resetting them to NULL
here as well.
Really, really, really need to get rid of this usercount handling
everywhere, hopefully incomming ID copying rewrite will help sanitize
that mess. But fix was needed for 2.79 release!
The code was somewhat weird: it was first copying border/crop settings from
the "source" scene, then was checking border settings of the current scene
and only then was copying border from "source" scene.
Now we first copy border/crop flags, then copy border from source and then
check whether border is a full-frame.
Auto & aligned handles wouldn't restore to their correct locations.
Note that a more direct fix for the bug is possible
(storing the handle locations to restore on cancel).
But that still gives some odd behavior, see code-comments for details.
The default anisotropic tangent computation could fail in some cases,
leading to NaNs and artifacts. Use a simpler formulation that doesn't
suffer from this.
The issue was caused by combination of following factors:
- Blender Internal viewport render can not distinguish between which parts of
main database changed, so it does full database re-sync when anything is
tagged for an update.
This way, if any NodeTree (including compositor) is changed, Blender Internal
viewport is tagged for full render database update.
- With old dependency graph, scene-level drivers are evaluated on every
iteration of scene_update_tagged, even if nothing is tagged for an update.
This causes compositor drivers be evaluated quite often.
- Driver evaluation checks whether value was changed, and if so it tags
corresponding ID type as updated (this is what was telling viewport to do
render database update).
This check was quite stupid: current property value was checked against the
one coming from driver expression. This means, if driver value is outside
of the hard limit range of the property, the property will always be
considered updated.
The fix is to compare current property value against clamped value from the
driver.
New dependency graph is tacking root bone into account when building the graph.
This is required in order to get proper dependencies between bones. so we can
reliably use bones as targets from the same rig (and even indirect relations
via external objects). This forces us to tag relations for update when we change
root IK chain bone.
Since relations rebuild is not fully trivial operation, we only do it for
the new dependency graph. In the future it'll be nice to avoid whole graph
rebuild for such cases, but that's mentioned as a TODO.
This situation happens when a file with a text effect sequencer strip is
loaded in Blender < 2.76 and saved. This destroys the effect data, causing
a crash in Blender ≥ 2.76.
d2f748a222 prevented the crash when opening such a file, but accessing
the strip still caused a crash. This commit fixes that by actually
initialising the invalid strip. Of course this still causes data loss, but
that already happened by opening & overwriting the file in Blender < 2.76.
Using an arbitrary face as the source of the UV data is mostly fine, as
vertices on seams will generally map to different parts of the texture
that have the same color.

Clearing of custom bones outline's line thickness was not done at proper
point, wireframe drawing never changes line thickness, only solid draw
with outline does...
Last fix only accounted for direct changes to the RB settings, but
failed for, say, object transformations. This fix accounts for any
change that might invalidate the RB cache.
