Concepts for the Term : Visual

Hihi ..
	Sorry , I would like to ask a question on the
	visuals.....

	The concepts on Visual described in the Manual
	is "Simply something you can draw on".

	After reading the declaration of the ggi_visual_t
	in internal/structs.h , it seems to be some kind 
	of "device context" specifying the gamma , frame
	buffer currently used , colormap ...etc.

	The mentioned "it can be an X-Window" is done
	by using multiple visuals representing multiple
	windows....

	The main functions of visual is still a full screen
	buffer ... Am I right ??

	It's also mentioned that the visual can be a memory
	space , can we dynamically move the memory frame??

	Sincerely ,
	Eric
