Tell the video driver that we only want a double buffer.
By default, most lowlevel 2D APIs will use a triple buffer scheme that
wastes no CPU time on waiting for vsync after issuing a flip, but
introduces a frame of latency. On the other hand, using a double buffer
scheme instead is recommended for cases where low latency is an important
factor because we save a whole frame of latency.
We do so by waiting for vsync immediately after issuing a flip, usually
just after eglSwapBuffers call in the backend's _SwapWindow function.
This hint is currently supported on the following drivers:
- Raspberry Pi (raspberrypi)
- Wayland (wayland)
This hint should be set before SDL is initialized.
