CVE-2022-2832 (https://developer.blender.org/T99706):
https://developer.blender.org/D15463
https://developer.blender.org/rB00dc7477022acdd969e4d709a235c0be819efa6c

When rendering with headless builds, show an error instead of crashing. Previously GPU_backend_init was called indirectly from DRW_opengl_context_create, a new function is now called from the window manager (GPU_backend_init_once), so it's possible to check if the GPU has a back-end. This also disables the bgl Python module when building WITH_HEADLESS.

CVE-2022-2833 (https://developer.blender.org/rB24a2b5cb1292f769dd86e314471443976d5e9512):
https://developer.blender.org/T99711

Endless Infinite loop in Blender-thumnailing due to logical bugs.

Looks like a fix for the second issue made it into 3.2.2.
