The Sprite
command does not affect the canvas directly because it does not
draw into it. It only draws to the screen when Draw
Frame is called.
This command draws the image
into the canvas. Once it has been drawn there it will stay until
it is drawn over by something else.
image is the index into the image bank of the image
to be drawn.
bank is the bank to get the image out of. The bank
must be loaded otherwise nothing will be drawn. If this is not
specified then the default bank is used.
x and y are co-ordinates in the canvas of
where to place it.
