To be fair, it does need to cover a few more subsystems, and how XFree86
behaves, as opposed to how DDXes should behave. But still, yes, it's a
very good start.

They're not half a million entirely tractable lines. How many people
can tell you what the input processing pipeline even vaguely is from
start to finish? Can you tell me, off the top of your head, the
subsystems involved in rendering and exactly what they do?
It's not that huge (and getting smaller every day, thank god), but the
reality is that you can't just look at one bit of code and go 'okay,
this does foo'. It's a tangled mess: actually being able to predict
what a piece of code viewed in isolation will do is something that
generally only comes after quite some time of context accumulation.
