exmouse - Getting input from the mouse. Allegro game programming library.

       This  program  demonstrates  how  to  get mouse input. The first part of the test retrieves the raw mouse
       input data and displays it on the screen without using any  mouse  cursor.  When  you  press  a  key  the
       standard  arrow-like  mouse cursor appears.  You are not restricted to this shape, and a second key press
       modifies the cursor to be several concentric colored circles. They are not joined together,  so  you  can
       still see bits of what's behind when you move the cursor over the printed text message.
