	render - librender, rendering routines for the WM and for apps
	parser - libparser, for parsing config files

Beware the Client.transient_for. It can be set to a !NULL value of TRAN_GROUP,
which is not a valid pointer. You must ALWAYS check for TRAN_GROUP before
following transient_for. However if it is transient for the group, this
excludes other windows whom are transient for the group, and windows which
are children of the window (infinite loops would result)!

When using coordinates/sizes of windows, make sure you use the right area. The
Client.area rect is the reference point and size of the *CLIENT* window. This
value is not what you see in any shape or form, and gravity is applied to it to
translate it into what you see. The Client.frame.area is the actual position
and size of the entire frame. This is usually the value you want to use, unless
you are in client.c (probably) and adjusting/using the position or size from
the client's perspective.

Indentation
-----------
For openbox, we aim to have consistent coding style. Some, but surely
not all, guidelines:
 * use 4 space indents
 * tabs should not appear in source files
 * functions should have the opening and closing braces on their own
   lines
 * most other constructs should have braces on the same line as the
   statement
 * else appears on a new line, just like an if
 * when in doubt look at the rest of the source
 * vim users can use "set expandtab tabstop=4 shiftwidth=4
   softtabstop=4" for some of this
