Given an imagebox i with i.resize_forbidden = false and a valid image set, the
call t:fit(0, 0) would return two times "not a number".
This is because the code first does some calculations to get the input image
into the available space and then tried to do some calculations needed for
scaling images up.
The first calculation already gave us h == 0 == w, the second calculation would
then calculate 0/0. This results in NaNs.
This was only noticed because NaN is not a valid table index in lua.
Fix this by returning 0,0 if we have an image of width or height 0 after the
first calculation. Since 0x0 images are valid in cairo, this also fixes the same
bug with such images.

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.
