Subject: New test for overlays
While writting QNX Photon Overlay code I've found that the existent overlay test application is not enough, it performs too artificial tests - it always moves/resizes the overlay's viewport, but in the real life that happens very rare. So I decided to write new test (commonly base on testoverlay.c code) and called it testoverlay2 :)
moose.dat - raw 8 bit paletted data of the small movie. (It was a moose.gif, also included in the attachment as reference, but not needed for this test, it is just for information). I cannot find, who created this .gif, so no credits this time :) But over inet I saw this gif zillion times, so I think we do not infringing somebody rights :)

The hardware will wait for vertical retrace, and then swap video buffers before the next video surface blit or lock will return\&.
