mainly because this is the way event apis in x, directfb etc. work :) they
report what button was pressed/released as an integer and have a separate button
mask for the currently pressed buttons :) (having a mask would make it hard to
figure out what button was pressed/not pressed on each press/release event) :)
if i now provided a previous/current mask u could.. but u'd have to loop thru
checking bits or do a subtract and based on the return val figure out what
button... etc. its just easier this way :)
