Configures the maximum allowed number of frames in flight.
The default value when the device is created is 2. This means that after
you have submitted 2 frames for presentation, if the GPU has not finished
working on the first frame, SDL_AcquireGPUSwapchainTexture() will fill the
swapchain texture pointer with NULL, and
SDL_WaitAndAcquireGPUSwapchainTexture() will block.
Higher values increase throughput at the expense of visual latency. Lower
values decrease visual latency at the expense of throughput.
Note that calling this function will stall and flush the command queue to
prevent synchronization issues.
The minimum value of allowed frames in flight is 1, and the maximum is 3.
