i'm workin on a game, and doin basically the same thing you want to do. what 
i did was pre-render like 36 or so images of each "ship". then, when the 
user presses the left/right keys, i just change the angle the ship is moving 
at. then, i my rendering, i just choose which of the 36 bitmaps to draw...

this works good, b/c the ship can be facing in any direction between 0 and 
360, down to the precision of float, but the way its gonna show up is one of 
36 different pre-rendered pictures... this works real good for me...  :-)
