When OSL is enabled, Cycles disables RTTI in some of its modules, which
then breaks vptr sanitizer (part of the 'undefined' sanitizer).
thanks to @brecht for helping tracking down the issue.
If image buffer is not loaded and blender attempts to reload it (during
`BKE_image_acquire_ibuf`) over and over for each frame rendered.
When attempting this reload, image_load_image_file is calling
`BKE_image_free_buffers` and tag the Image to the (GPU) image_free_queue
(because this run on the rendering thread).
If the main thread decide to redraw the UI and go through `GPU_free_unused_buffers` they all get deleted and if that happens before the rendering thread use them ... segfault.
If I replace the environment textures with correct ones (the file does not seems to contain them), there is no crash when rendering.
I used a list of GPUTexture from blender Image to increase and decrease the
reference counter correctly.
This add very little memory and computation overhead.
Since it is a continuous cycle, there's no need to repeat the
name of the previous bone. Also, dot is a common symbol in object
and bone names, so use '/' instead for node nesting.
Add a callback to allow custom node editors to draw their own
backdrop.

Targeting a different object always requires its transform,
and normally dependencies should go to the solver node.
ITASC is quite broken so special case it until fixed.
As far as I can tell, there is no technical reason why the B-Bone
segment thickness scaling can't be separated into two axes. The
only downside is the increase in complexity of the B-Bone settings,
but this is inevitable due to the increase in flexibility.
Updating the file is somewhat complicated though, because F-Curves
and drivers have to be duplicated and updated to the new names.

Currently it is not possible to view the vertex colors of an object. To
optimize the workflow, workbench will need to support Vertex Colors.
The Vertex Colors is a new option in `shading->color_type`. When objects
do not have vertex color, the objects will be rendered with the
`V3D_SHADING_OBJECT_COLOR`.
In order to support vertex colors in workbench the current texture/solid
shading structure is migrated to a primary shaders and fallback shaders.

I did not rename the other property to `show_expanded_dopesheet`
yet (as suggested in the report), because:
* Would break compatibility (haven't found any addon using it though).
* I'm not sure if this really only affects the dopesheet.
- Resizable areas use 2D view bounds.
- Header uses the button bounds.
- A margin is added to avoid clicking between buttons.
- Region resize edges clamp to the 2D view bounds.
