When bl_use_gpu_context is set, an OpenGL context will be available for
OpenGL based render engines.

Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.

When the mesh is linked, the materials can not be available or be the same assigned to mesh. Now, if the mesh is linked, a simple two materials conversion is used.
To get the full list of materials, the mesh must not be linked.
Also checked some indexes to be sure never get a wrong value and that materials are not created again and again.

Use binary search for querying deform weights.

During profiling it was detected that adding new items to the head was faster than adding to the tail.

This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/editors/gpencil` module.
No functional changes.

This is because the DRW module is no longer compatible with drawing using
MSAA.
This also change the Python API.

When drawing a primitive, the color was always assigned as vertex color, so it was impossible to change it in the material settings.
Now, the color is set to material color or vertex color as expected.

This fixes the issue by using the polyline shader but this does not gives
the best results.
A better way would be to have a dedicated shader for the lines to avoid
the line break at every angle change.

Now, instead of select the section of the stroke that is below circle, only the points inside circle are selected.

If the object hadn't material, the index of material was negative.

The selection with the tweak tool was inprecise because it was using the bounding box and if the point was in a straight line in the border or in the corners it was very hard to select.
For this tool is better don't use the bounding box check.

When neither bounds or median is selected, snapping the cursor to
the selection was using bounds which often doesn't give useful results.

* Fixed selection of point in multiframe mode. The point was not selected.
* Removed the fill area selection because makes the tool imprecise, and for this tool need to be precise or the selection is impossible. Now only select if it's over the point, not over the filled area.

This was due some strokes could be tagged and as the layer was locked, the strokes were not untagged and removed when all tagged strokes are removed.
The tagged strokes are used as temp ghost of the interpolation and removed at the end of the interpolation.

Using enum type itself in implementations, and uint in headers (as using
enums types in headers is a pain when enum are not defined and used in a

This patch adds two options:
- Convert a mesh to grease pencil strokes.
- Bake the mesh animation into grease pencil strokes.
Both are related and must be included in the same patch.
Related to tasks: T77629 and T77630
Notice: The conversion is done for mesh edges and it's not considering any visibility clipping. All edges are exported, no matters if it's visible or not.
Example of Convert a Mesh to Grease Pencil strokes:

This conversion was inspired by the technique used by @luamono in this tweet: https://twitter.com/luamono/status/1239983662176841730
Example of Bake Animation (the video is a little outdate, but the basic functionality is the same, only small changes in UI):

Previously, the first frame was displayed from frame 0, but now, the first frame is only displayed when the current frame is equal or greater than the keyframe number.
The previous system was logical when the grease pencil was not an object, but now it seems more logical to display the keyframe if the current frame is equal to or greater than the keyframe number.

This caused an additional argument when exiting object modes
and many other low level functions which don't need to access context.

The Sculpt brushes were not properly initialized when use 2D template or other templates.
Also, using the default template (not factory settings) could be situations where the brushes were not updated.
This problem was introduced when some versioning code was removed in order to avoid duplicated brush creation.
