The rendering code and the event handling code are in the same file usually 
(XXterm.c).
They might be logically separated or logically independent.  We are also using 
GC:s in the core drawing routines, or an emulation of GC:s, but they are really 
an X system thing.  There are other X-isms that a pure renderer has to deal 
with.
