Detailed Description

Implementation of Bitmap and BitmapUpdate: RGBA raster storage, drawing primitives, integer-ratio resizers, BMP file (de)serialization and the RLE/difference codecs used for incremental remote-display updates.

See Bitmap.h for the pixel layout (top-down RGBA, R in the lowest byte) and buffer-ownership rules the routines here rely on.

#define D	(		r,
			y )

Value:

(ceil(sqrt((double)r*r - y*y)) - sqrt((double)r*r - y*y))
