New feature for the %xl (image load) tag. If you give it the filename __list_icons__ it will use the list icon strip instead of loading a different bmp.

example:
%xl(I, __list_icons__, 0, 0)
%xd(I, %Li)

^ display the list icon at position 0,0 in that viewport. (you can of course %xd(Ia) if you really wanted also.)
