Minimal test program to demonstrate bug

Compile with: cc $(pkg-config --cflags --libs x11) -o fbc-bug-xlib fbc-bug-xlib.c

Draws random-colored pixels with XPutImage to exercise a bug in the
frame-buffer compression code in the xf86-video-intel 965 driver.

When a driver has the bug, rendering from this program will appear
to "freeze" every 15 seconds or so, (until the window is moved or
its decorations are redrawn, etc.).
