Make FPS controller.

FPS controller is a block that must be called once in a rendering loop. It will put a thread to sleep to achieve a specified amount of frames per second. This block returns FPS controller status (see vox_fps_info).

Parameters

fps	A desired FPS value. If it's zero, only count FPS, do not put a thread to sleep.

Returns

FPS controller status.
