Movieclip: Use first clip frame for size detection

Using scene frame 1 is not reliable in cases when there is a
frame offset is involved. Using frame 1 seems more reliable,
although might still fail under certain circumstances.

More reliable fix would require a deeper change in the data
structure and the logic about frame loading and size detection.

Fix T87926: Transform menu has operators guaranteed to not pass poll in certain modes

Reported for ops.transform.vertex_warp and ops.transform.vertex_random.
Polling will check with ED_transverts_check_obedit, if we know it will
fail e.g. for pose mode, we can do the same check in the UI already.

Fix T88005: GPencil inverse fill leaves unwanted line at viewport edge.

There was a function to set 2 pixels wide for inverse filling, but this must not be done in the borders of the image.

Now, the borders are checked before set 2 pixels.

Geometry Nodes: Initial basic curve data support

This patch adds initial curve support to geometry nodes. Currently
there is only one node available, the "Curve to Mesh" node, T87428.

However, the aim of the changes here is larger than just supporting
curve data in nodes-- it also uses the opportunity to add better spline
data structures, intended to replace the existing curve evaluation code.
The curve code in Blender is quite old, and it's generally regarded as
some of the messiest, hardest-to-understand code as well. The classes
in `BKE_spline.hh` aim to be faster, more extensible, and much more
easily understandable. Further explanation can be found in comments in
that file.

Initial builtin spline attributes are supported-- reading and writing
from the `cyclic` and `resolution` attributes works with any of the
attribute nodes. Also, only Z-up normal calculation is implemented
at the moment, and tilts do not apply yet.

**Limitations**
- For now, you must bring curves into the node tree with an "Object
Info" node. Changes to the curve modifier stack will come later.
- Converting to a mesh is necessary to visualize the curve data.

Further progress can be tracked in: T87245

Fix (unreported): 'CoInitializeEx' being called without 'CoUninitialize'

Problem introduced in {rB1f223b9a}.

This was possibly causing random crashes in Blender file browser when
compiled with ASAN.

Microsoft documents indicate that any call to `CoInitializeEx` must be
balanced by a corresponding call to `CoUninitialize`.

Geometry Nodes: refactor instances component

The main goal of this refactor is to not store Object/Collection
pointers for every individual instance. Instead instances now
store a handle for the referenced data. The actual Object/Collection
pointers are stored in a new `InstanceReference` class.

This refactor also allows for some better optimizations further down
the line, because one does not have to search through all instances
anymore to find what data is instanced.

Furthermore, this refactor makes it easier to support instancing
`GeometrySet` or any other data that has to be owned by the
`InstancesComponent`.

Fix T86450: Random dark UI elements when redrawing

Resolves occasional glitch/flicker drawing dark buttons in the UI.

Regression in 405a5d3bd7ada5dd5af605b59ba07c7144f144a2
which removed shader unbinding when the batch is drawn.

GPU_shader_bind could run with the sRGB uniform in an unexpected state.

Fix T87905: GPencil modifiers not applied if saved with multiframe

Now the multiframe is not enabled if it's doing a render.

UI: Object Thumbnails Orientation Change

Object orientation for thumbnail creation changed to be slightly
oblique (tilted to one side and from above) to better show shape,
especially when axis-aligned. Camera lens changed to 85 to avoid
distortion of close objects like human heads.

Fix T82824: Draw sensor size with correct alpha

Previously the option in the camera's //Object Data Properties > Viewport Display
> Sensor// would not display the sensor in camera view. This seemed to be caused
by the theme color `TH_VIEW_OVERLAY` having zero set for the alpha channel and
alpha blending being active, resulting in no visible output. Hence
`immUniformThemeColorShade(TH_VIEW_OVERLAY, 100);` is replaced with
`immUniformThemeColorShadeAlpha(TH_VIEW_OVERLAY, 100, 255);`.
