-/* Draw test patterns to help determine correct gamma value for a display.
-   When the intensities of the inner squares nearly match the intensities
-   of their frames (from some distance the borders should disappear) then
-   you've found the right gamma value.
-
-   You can set Mesa's gamma values (for red, green and blue) with the
-   MESA_GAMMA environment variable.  But only on X windows!
-   For example:
-        setenv MESA_GAMMA 1.5 1.6 1.4
-   Sets the red gamma value to 1.5, green to 1.6 and blue to 1.4.
-   See the main README file for more information.
-
-   For more info about gamma correction see:
-   http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
