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

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.
