Groovie V2 uses cursors with a 4bit alpha, however for simplicity I 
currently treat it as a 1bit alpha.  This would be to smooth the edges 
of the cursors out (currently it's a little jagged) and presumably to 
implement the translucent cursors that the original has.   Although IMO 
the fully solid ones look better.
