maybe i could get it to run even faster if i did both tasks at once...

i need to make a copy of the pixels from the location on the screen where 
the new ones are going, before puting my image onto the screen.  this is so 
that i can put them back when im done displaying the picture.  i only want 
to copy the pixels where the non-transparent pixels of the image are going, 
the rest i'll fill out with the transparent color.

i should tell you that i am not writing directly to the screen, instead i'm 
putting all the bitmap information into a sequence the same size as the 
screen, then displaying that on the screen  -  it reduces flicker.

at the moment, it works.  it just runs like shit through a seive.  please 
help :)

thanks in advance.
