This is an incremental patch with my first try to fix these error handling
problems. I'm not sure if this is the correct way to handle errors as I am a
Xlib-newbie. It seemed cleaner to me to release resources if things fail after
some allocations succeeded. Furthermore, there's a lot of code duplication,
which in Linux is avoided by using gotos :) I could also make a function that is
called on every failure and does all the releasing using one "if (!...)"
condition per call.

With friendly regards,
