It affects many aspects of the drawing; it saves you passing 20 parameters
to all the drawing functions. Look at the gdk_gc_* functions in gdk.h to
get an idea. You'll probably have to read the Xlib Programming Manual
(which may be online somewhere, but is published by O'Reilly) if you
really want to know. It's a bit too involved to just explain.
