+// 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.
