Method	Description
Blit ( BitmapData source, BitmapData target, Rectangle sourceRect, int px, int py ) : void	Blits from source to target. Both source and target must be 32-bit
Blit ( BitmapData source, BitmapData target, int srcPx, int srcPy, int srcW, int srcH, int destX, int destY ) : void	Blits from source to target. Both source and target must be 32-bit
BlitMask ( BitmapData source, BitmapData target, int srcPx, int srcPy, int srcW, int srcH, int px, int py ) : void	Blits a block of a bitmap data from source to destination, using the luminance of the source to determine the alpha of the target. Source must be 24-bit, target must be 32-bit.
