By allowing to set the delay between frames with milliseconds precision in the command line, we can use it to test vsync. Signed-off-by:Siarhei Siamashka <siarhei.siamashka@gmail.com>

The test program cycles through 3 colors (red, green, blue), so it is easier to see if we get the color change pattern wrong. Also the X11 window title is updated to indicate the current color information. If we have any problems with window decorations handling, they are likely to be exposed. Signed-off-by:

This test program exposes a problem related to window resizing (or going fullscreen), which is may happen exactly between "back" and "front" DRI2 buffers allocation.
