					   y_bitmap - Generate bitmaps.
					=================================
Description:
	Code to generate images on the server in the bitmap format.  This is by far
	the simplest format to write to as it is just a huge array of colours (at
	least 24-bit bitmaps are, and we only do them).
	
	This file contains functions to draw various shapes.

<remarks>
	This function draws a rectangle between two given co-ordinates.  It can also
	draw a border around the rectangle OUTSIDE the specified area of the
	rectangle.  If you want the border within the area specified you need to use
	a smaller area.
