// Description:

// TMULSCREENS.CPP

// Tests the newly API function added to RWindow which enables/disables

// the usage of Off-Screen Bitmap (OSB).

// The test will draw squares with random colours on screen filling the

// whole drawable area. The drawing will start first with flickering screen

// and will switch to flicker free in 4 seconds.
