SDL_AcquireGPUCommandBuffer - Acquire a command buffer.

       This function is available since SDL 3.2.0.

       This  command  buffer  is  managed by the implementation and should not be freed by the user. The command
       buffer may only be used on the thread it was acquired on. The command buffer should be submitted  on  the
       thread it was acquired on.

       It  is  valid  to  acquire  multiple  command buffers on the same thread at once. In fact a common design
       pattern is to acquire two command buffers per frame where one is dedicated to render and  compute  passes
       and  the  other  is  dedicated  to  copy  passes  and  other preparatory work such as generating mipmaps.
       Interleaving commands between the two command buffers reduces the total amount of  passes  overall  which
       improves rendering performance.
