 // 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.
