The X11 server tells us about things that need to be redrawn via expose events.
When we get such an expose event before lua drew the drawable, we just fill the
exposed area with old data (which is black for newly-created drawables).
Fix this by tracking if we have any usable data in a drawable's double buffering
pixmap. This flag is unset whenever we throw away the old content (e.g. due to a
resize) and is set when lua gave us some new content to display.

awesome
=======
awesome is a highly configurable, next generation framework window manager for X.
Building and installation
-------------------------
After extracting the dist tarball, run:
make
This will create a build directory, run cmake in it and build awesome.
After building is finished, you can install:
make install # you might need root permissions
Running awesome
---------------
You can directly select awesome from your display manager. If not, you can
add the following line to your .xinitrc to start awesome using startx
or to .xsession to start awesome using your display manager:
exec awesome
In order to connect awesome to a specific display, make sure that
the DISPLAY environment variable is set correctly, e.g.:
DISPLAY=foo.bar:1 exec awesome
(This will start awesome on display :1 of the host foo.bar.)
Configuration
-------------
The configuration of awesome is done by creating a $XDG_CONFIG_HOME/awesome/rc.lua file.
An example configuration named "awesomerc.lua.in" is provided in the source.
Troubleshooting
---------------
In most systems any message printed by awesome (including warnings and errors)
are written to $HOME/.xsession-errors.
If awesome does not start or the configuration file is not producing the desired
results the user should examine this file to gain insight into the problem.
