Detailed Description

Simulates a v-sync pause using sleep.

limit should be called once at the end of each frame. A constant rate of 60FPS, scaled by the inverse of interval, is maintained no matter the duration between each call to limit.

If one cycle takes too long, limit returns immediately a number of times necessary to generate the correct amount of frames as if the rate had been maintained (i.e. frames are not skipped).
