	* HACKING: Add lots of information to extend this document: more
	on relevant standards and X properties, lots of information on
	debugging and testing, and add a list of some other important
	things to read; also move some information to
	src/code-overview.txt and organize this file into sections.

	* src/code-overview.txt: New file including some small parts from
	the old HACKING file and lots of new stuff.  This file gives a
	brief overview of some of the bigger structures and files, with
	guides for a variety of task categories providing places to start
	looking in the code and things to look for.
