NAME
       exrgbhsv - RGB <-> HSV color space conversions. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


       Example exrgbhsv

DESCRIPTION
       This program shows how to convert colors between the different color-
       space representations. The central area of the screen will display the
       current color. On the top left corner of the screen, three sliders allow
       you to modify the red, green and blue value of the color. On the bottom
       right corner of the screen, three sliders allow you to modify the hue,
       saturation and value of the color. The color bars beneath the sliders
       show what the resulting color will look like when the slider is dragged
       to that position.

       Additionally this example also shows how to "inherit" the behaviour of a
       GUI object and extend it, here used to create the sliders.
