Initializes the Super 2xSaI library. This must be called before calling
a filtering procedure.
depth: the color depth to use when filtering. source and destination
bitmaps must use this color depth.
Enlarges a bitmap by 2x magnification using the Super 2xSaI filter. The
destination bitmap dimensions must be at least
(dx+width*2-1) by (dy+height*2-1).
src : the source bitmap
dest : the destination bitmap (must be large enough!)
sx, sy: the source bitmap coordinates
dx, sy: the destination bitmap coordinates
width : the width of the area from the source bitmap to scale
height: the height of the area from the source bitmap to scale
Enlarges a bitmap by 2x magnification using the Super Eagle filter. The
destination bitmap dimensions must be at least
(dx+width*2-1) by (dy+height*2-1).
src : the source bitmap
dest : the destination bitmap (must be large enough!)
sx, sy: the source bitmap coordinates
dx, sy: the destination bitmap coordinates
width : the width of the area from the source bitmap to scale
height: the height of the area from the source bitmap to scale
