Detailed Description

Manage GL vertex array IDs in a thread-safe way Use these instead of glGenBuffers & its friends

alloc must be called from a thread that is bound to the context that will be used for drawing with this VAO.
free can be called from any thread

◆ GPU_backend_type_selection_detect()

bool GPU_backend_type_selection_detect ( )

Detect the most suited eGPUBackendType.

The detected backend will be set in GPU_backend_type_selection_set.
When GPU_backend_type_selection_is_overridden it checks the overridden backend. When not overridden it checks a default list.
OpenGL backend will be checked as fallback for Metal.

Returns true when detection found a supported backend, otherwise returns false. When no supported backend is found GPU_backend_type_selection_set is called with GPU_BACKEND_NONE.
