* opengl_context -> system_gpu_context. This is the operating system OpenGL, Metal or Vulkan context provided by GHOST. * gpu_context -> blender_gpu_context. This is the GPUContext provided by the Blender GPU module, which wraps the GHOST context and adds some state. * Various functions create/destroy/enable/disable both contexts, these have just gpu_context in the name now.
