When introducing "drag-all-selected" support all over Blender, we
figured this wouldn't work well with the Graph Editor
selection/transform behavior.
Hence, William and I worked on the following changes, although we used
this chance to improve the behavior in general too.
For more info see T70634.
* Handles now always move with the key, regardless if they are selected
or not.
* Selecting the key doesn't select the handles anymore, their selection
is separate.
* Multiple keys and handles can now be dragged.
* Dragging a handle moves all selected handles **on the same side**.
* Tweak-dragging any handle can never affect any keyframe location,
only handles.
* G/R/S should behave as before.
* Changing the handle type with a key selected always applies the change
to both handles.
* Box selection with Ctrl+Drag now allows deselecting handles (used to
act on entire triple only).
* Box selection //Include Handles// option now only acts on visible
handles, wasn't the case with Only Selected Keyframes Handles enabled.
* Box selection //Include Handles// is now enabled by default in all
bundled keymaps.
The changes have been tested for some days by the animators here in the
Blender Animation Studio. Some changes are based on their feedback.
Also, this improves/adds comments for related code.

These were only strictly valid for texture space calculation, don't store them
since they should not be used after that. Only store a flag to indicate if the
auto texture space has been evaluated.
In the future it might make sense to store bounding boxes at the mesh level to
speed up bounding box computation for multiple objects using the same mesh, but
then it will need to be implemented differently.
There are several aspects to the fix:
- Always calculate bounding box for meshes and curves from dependency
graph evaluation function.
There is a reason why mesh was tagged for geometry update, so can not
be spare here in attempts to avoid calculation.
- Copy bounding box and texture space to original object for active
dependency graph.
This matches object-level bounding box and allows to remove bounding
box evaluation from RNA.

Such data is to be evaluated by a dependency graph.
Don't see a reason to be different here: we never force evaluation of
any kind from RNA.

This is old logic that no longer makes sense in the new depsgraph, and causes
issues when multiple threads try to modify the same bevel object.

Curve function had two arguments:
- for_render, which was originally supposed to be used to control
whether viewport or render visibility for modifiers is to be
used.
- use_render_resolution, which sounds like it is supposed to control
whether viewport or render resolution for curves is to be used.
What is totally confusing is that those arguments were used
interchangeably: sometimes use_render_resolution would control
modifiers visibility.
This commit makes it so there is one single argument for this.

Use the term "AFTER" instead of "OFS" since it wasn't obvious these
macros operate on everything after the struct member passed.
Avoid casting to non-const types when only reading.
This was caused by curves pointing to each other
creating a cyclic dependency.
While the dependency graph detects this, generating a mesh for render
recursively generates data which cashes in this case.
Add in a check to detect cyclic links.
Note, this bug exists in 2.7x too - but only crashes on render
since 2.7x didn't use 'for_render' when converting data.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.
Fixes T58632: Particle don't update rotation settings
Thinks whole bbox code needs a complete rewrite, one can see a lot of
old history in it, it has way too many functions doing
nearly-the-same-thing(c), it spreads in very inconsistent ways across a
lot of files, ... But have no time for this right now, and would not be
a good idea with Beta comming up close anyway.
So for now going the simple and (hopefully) sane & safe way: forbid
object-level functions to affect data-level bbox. Mesh and curve ones
would generate bbox in obdata instead of object, for some reason (all
other obdata types only use object's bbox ever). That may have been
working in old ages, but with CoW and threaded depsgraph this is just
calling for piles of issues.
Use `BKE_curve_texspace_get` instead `BKE_curve_boundbox_get`.
The snap to curve, even out of edit mode, is not done on the displist. So test a boundbox that covers the points seens in edit mode.
