Sure, but.. if this sprite is going to do anything useful - like in a tile
based game, it is going to be hard to stuff with 19 pixel height. The screen
height is 100, so why make it 19 high? I would either make it 8 pixels high,
16, or (to be evenenly divisble by 100) 10. At least with 10, you can code
it by shifting twice and adding twice, like

Tile ROW 15 * 10 = 15 shifted twice (15*8) + 15 + 15
                               = 120 + 30
                               = 150 pixels down from screen

Easy? Now try that with 19 height :)
