This resolves a performance regression in 2.8x where every edit-mode
update performed an edit-mesh to mesh conversion.
Now the conversion will be lazily initialized if/when it's required.
New BKE_mesh_wrapper_* functions abstract over mesh data access.
Currently only edit-mesh and regular meshes are supported.
In the future sub-surface meshes may be supported too.
Add TBB::flow graph scheduling to BLI_task.
Using flow graphs, a graph of nodes (tasks) and links can be defined.
Work can flow though the graph. During this process the execution of the nodes will be
scheduled among the available threads.
We are planning to use this to improve the threading in the draw manager.
The implemented API is still limited it only supports sequential flows. Joins and buffers
are not supported. We could eventually support them as part of an CPP API. These features
from uses compile time templates and are hard to make a clean C-API for this.

Lamps were not tagged with `ID_RECALC_SHADING` when they were updated
from drivers. As a result, Cycles considered the lamp as unchanged. This
is resolved by having a (seemingly non-functional) callback in a new
`LIGHT_UPDATE` depsgraph node.
This patch unconditionally adds the `LIGHT_UPDATE` node + the relation
from the lamp's PARAMETERS node.

The `BM_mesh_bm_to_me()` function copies shape keys from the BMesh to
the Mesh. However, it tries to copy the same number of shape keys as are
defined on the target mesh. Since the target mesh does not necessarily
have the same number of shape keys as the BMesh, this would crash if the
target Mesh has more.
Found while performing some tests for {D7785}.

While investigating T76274, I found crash scenario when playhead is near end
frame and moving a strip. It is not as easy to reproduce, about 5% success
rate, and it will be even harder after rB4066c921fbe5. Exact cause wasn't
identified yet.
I wanted to disable prefetching during modal operator execution in VSE, but
currently I don't have any signalling method in place. Checking for G.moving

Blender's main loop puts the main thread to sleep for 5ms if no user input was
received from the OS. We never want that to happen while the VR session is
running, which runs on the main thread too.
For simpler scenes, where the viewport already draws fast, this may have quite
some impact. E.g. in my tests, the classroom scene went from ~55 to quite
stable 90 FPS in solid mode (total render time as measured and averaged by
Windows Mixed Reality utilities). With Eevee, it only went from 41 to 47 FPS.
In complex files, there's barely a difference. E.g. less than 1 FPS increase in
a Spring file (both Solid mode and Eevee).
The operators to open the Preferences, Driver Editor, or Info Log window did
not work when executed from another operator or the Python console. Should work
for all of these now.
I considered using operator properties instead, so the position could be set by
a script, with some fallback (e.g. current window center). But decided that's
not really worth the boilerplate and decreased code readability. Can still be
done if there's a need for it.
Allow setting drivers and keyframes for the bone visibility restriction
icon in the outliner. Before the button was a simple icon button, but it
is now connected to the RNA property to show the driven or keyframed
state.
Also when hiding a bone from the outliner it would be deselected, but
from the properties editor it would remain selected. This moves the
deselection to the RNA update function to ensure the bone is always
deselected.

If the redo panel was made visible with the same size it had before
(e.g. stored in the file), the runtime region coordinates wouldn't get
set and ended up being all 0. E.g. the simplest way to cause this was
having a collapsed HUD, saving the file, re-opening it with the same
effective DPI and doing an operation so the closed HUD would appear
again.
Now the size is always recalculated if the visibility state of the HUD
changes.
We define Lossless as CRF 0 (which is usually the best quality and is
working fine with other codecs afaict), but since WebM only allows for
CRF values between 2-32 and actually has a dedicated "lossless" mode, I
suggest using that (it produces large files though, so double-checking
would be welcome).

This feature was added when Blender used tex-face (per-face images),
but doesn't make as much sense since this was removed.
Removing this from UV edit-mode as this wasn't working in any
of the 2.8x releases, causing UV's to be visible but unselectable.
Resolves issue raised in T76958.
All textures in workbench are using linear interpolation. The fragment
shader modifies the uv coordinates to sample always in the center of a
texel. In rare conditions the GPU could sample an incorrect value due to
rounding errors making some rendering artifacts.
This patch skips the interpolation in the fragment shader to remove
these render artifacts.

This bug is not really visible for user. When end frame is reached by
prefetching thread, it doesn't stop and keeps on getting images from
cache.
