Previously, hitting Shift-LMB will first invoke selection operator, which
then later on is transformed to mouse tweak used for reroute operator.
This was causing problems extending selection with Shift-LMB when clicking
fast or from a tablet.
Avoid creating new Python instances
every time a scene, object, mesh .. etc are accessed.
Also resolves crashes T28724, T53530
although it's only valid for ID types, not modifiers vertices etc.
Back-ported from blender2.8 branch.
Bug introduced on rB9f5bf197a0c3.
The offset for selection of vertices (`bm_vertoffs`) starts where the offset o edges ends (`bm_wireoffs`).
However, the `bm_wireoffs` depends on the offset of face selection (`bm_solidoffs`).
Before the commit that introduced the bug, the drawn of edges (in backbuff) was always computed along with the `bm_wireoffs`:
```
bm_wireoffs = bm_solidoffs + em->bm->totedge;
```
Now that the edges are not always drawn in backbuff, `bm_wireoffs` has to start from `bm_solidoffs`.
Our own implementation was behaving different comparing to OSL and GPU,
namely on the border pixels OSL and CUDA was doing interpolation with
black, but we were clamping coordinate.
This partially fixes issue reported in T53452.
Similar change should also be done for 3D interpolation perhaps, but this
is to be investigated separately.
This only applies to ID being copied outside of bmain. Handy for cases when it
is important to check if the copy corresponds to a data block coming from
library.
Example of that is proxy evaluation with copy on write.
Thanks Bastien for review!
Before that it was up to lots of other places to keep track on whether
something is to be dependent on time or not. Was annoying, and unreliable,
and fragile.
This commit avoids hacks in object builder. Other areas will be adopted
soon.
This is something what should be supported by the new dependency graph.
Fixed by making it so, build_animation() adds relation between Animation
component and whatever-is-being-animated. In fact, for now, only relations to
ID properties are added. Rest of the relations are kind of hacked in all over
the code and needs to be removed and verified with specific .blend files.
We can't use a single component here, sine it might consist of multiple
operations. So, for example, having driver operation will confuse targets
of another driver.
