I am attempting to develop a graphical interface for gnuchess.
Does anyone know of a graphics library (commercial or public) that:

	1. Lets you set the 1024x768, 800x600, or 640x480 mode.
	2. Has functions for the above modes that let you read/write a
	   X by Y bitmap from/to any screen location.

Also, is anyone familiar with the format of .pic files produced by
Dr.Halo ? I suspect that these files have a preamble that contains
information such as X,Y dimension and page offset of the image. It
follows that one would also need to know how the file data relates to
display memory, i.e. is the data sequentially organized or in some 
other fashion ?
Thanks for your help.
