Now that we use libdockapp's --windowed option to allow users to choose
whether to run fookb as a dockapp or as a normal windowed application at
runtime, the --enable-wmaker option compile time option did very little.
In particular, it used a config file in ~/GNUstep/Defaults and it printed
a warning message when users used large icon files.
We now use the ~/.fookb config file in all instances and always print the
warning message.
In addition to the obvious simplification to the code by removing all the
window creation stuff, this also allows us to let users pick whether they
want to run fookb as a dockapp or as a normal windowed application at
runtime using libdockapp's --windowed command line option. Previously,
this was done during build using configure's --enable-wmaker option.
Previously, we would try and read the width and height of images read from
an XPM file *before* doing any error handling to determine whether we
successfully read the file in the first place. If there had been an error,
then there would be a segfault.
