To clarify term still frame: This is portion of strip that displays
static image. This area can exist before or after strip movie content.
Still frames were implemented as strip property, but this was never
displayed in panel. Only way to set still frames was to drag strip
handle with mouse or using python API. This would set either
`seq->*still` or `seq->*ofs` where * stands for `start` or `end`.
When strip had offset, it can't have still frames and vice versa, but
this had to be enforced in RNA functions and everywhere in code where
these fields are set directly. Strip can not have negative offset or
negative number of still frames.
This is not very practical approach and still frames can be simply
implemented as applying negative offset. Merging these offsets would
simplify offset calculations for example in D14962 and could make it
easier to also deprecate usage `seq->*disp` and necessity to call
update functions to recalculate strip boundaries.
For users only functional change is ability to set negative strip offset
using property in side panel.

Issue revealed by rB90e12e823ff0. Hidden objects may not be fully
evaluated by the despgraph, do not attempt to restore edit/sculpt/etc.
modes for those.
Should also be backported to 2.93 LTS release.
Sometimes integers are mixed using float weights. In those cases
the mixed result has to be converted from into float again.
Previously, this was done using a simple cast, which was unexpected
because e.g. 14.999 would be cast to 14 instead of 15.
Now, the values are rounded properly.
This can affect existing files unfortunately without a good option
for versioning. Gladly, very few files seem to depend on the details
of the old behavior.

This makes changes to the opensubdiv module to support additional vertex data
besides the vertex position, that is smootly interpolated the same way. This is
different than varying data which is interpolated linearly.
Fixes T96596: wrong generated texture coordinates with GPU subdivision. In that
bug lazy subdivision would not interpolate orcos.
Later on, this implementation can also be used to remove the modifier stack
mechanism where modifiers are evaluated a second time for orcos, which is messy
and inefficient. But that's a more risky change, this is just the part to fix
the bug in 3.2.

Previously, the depsgraph assumed that every node tree might contain
a reference to a video. This resulted noticeable overhead when there
was no video.
Checking whether a node tree contained a video was relatively expensive
to do in the depsgraph. It is cheaper now due to the structure of the new
node tree updater.
This also adds an additional run-time field to `bNodeTree` (there are
quite a few already). We should move those to a separate run-time
struct, but not as part of a bug fix.

If making liboverride of an empty collection, this (root of override
hierarchy) collection would get untagged in code when checking for
collections that do not need to be overridden, leading to not overriding
this root collection, and later in code to using NULL pointer.
It turns out there's no practical use for separating different edge types
before final occlusion stage, also using an array should be faster overall.
So changed those lists into one pending array, it also made the
iteration and occlusion task scheduling simpler.

This change allows the chaining function to select edges
from the same contour loop first, thus reduced rouge chain
connections (connected different objects instead of chaining
inside the same object first) and improved chaining quality.
This patch also included the default value change for chain
split threshold (Now don't split by default to make initial
result as smooth as possible)

Accessing context members depended on `ctypes` to access symbols
which were hidden for macOS & WIN32.
Add an API call that doesn't require the symbols to be exported.
This allows most symbols to be hidden on Linux, see D14971.
Regression caused by [0] which changed node selection to use
PRESS for selection and CLICK_DRAG to transform the selection.
This conflicted with Alt-LMB which would select the node then
pass-though to node.background_sample, preventing the drag event
from being activated.
Resolve by only activating background-sample when the cursor
isn't over a node or socket.

Issue was caused by treating such strip as meta and using
`seq->channels` directly, which is not valid for scene strips.
Pointer to channels is now provided by function
`SEQ_get_seqbase_from_sequence`.
We need to ensure `Main.filepath` is consistent with the current path
where we are saving the .blend file, otherwise some path processing code
can produce invalid results (happens with e.g. the code syncing the two
path storages in Library IDs).
The problem is that depsgraph evaluation happens before the OpenGL context
is initialized, and so modifier evaluation happens without GPU subdivision.
Later the BKE_subsurf_modifier_can_do_gpu_subdiv test in the draw code gives
a different result.
This just checks if the mesh has information for GPU subdivision in the draw
code, and if so uses it. This is only set if the test for supported GPU
subdivision passes in the modifier evaluation.
Additionally it may be good to perform OpenGL context initialization earlier
so background render can take advantage of GPU subdivision, but this is more
complicated.

This reverts commit 30534deced.
After discussion and feedback from users, it's better to keep this tool
available until there is time to properly re-think the whole Outliner's
contextual menu.
Properly use CLOG to report info or errors in `writefile.c`, instead of
printf's.
And remove some assert when logging error reports and the issue is not
critical.
If we produce CLOG_ERROR messages and the error is not actually
critical, there is no point in asserting too.
Mainly related to ID user counts, and a few other ID management areas.
