Gambas internally uses its own algorithm to get desktop icons from theme, 
because it needs to get the current icon theme first, which depends on the 
current desktop being used. Then it use a desktop-dependent method to get the 
path of the icon theme.

But the real algorithm you must follow is described by a freedesktop standard 
at:
