++/** @file glsync.c
++ * The program is simple:  it paints a window alternating colors (red &
++ * white) either as fast as possible or synchronized to vblank events
++ *
++ * If run normally, the program should display a window that exhibits
++ * significant tearing between red and white colors (e.g. you might get
++ * a "waterfall" effect of red and white horizontal bars).
++ *
++ * If run with the '-s b' option, the program should synchronize the
++ * window color changes with the vertical blank period, resulting in a
++ * window that looks orangish with a high frequency flicker (which may
++ * be invisible).  If the window is moved to another screen, this
++ * property should be preserved.  If the window spans two screens, it
++ * shouldn't tear on whichever screen most of the window is on; the
++ * portion on the other screen may show some tearing (like the
++ * waterfall effect above).
++ *
++ * Other options include '-w <width>' and '-h <height' to set the
++ * window size.
