besides xpm. to get imlib2 support in fluxbox one has to
./configure --enable-imblib2
default is disabled. a fluxbox-binary that supports imlib2 will have
IMLIB2 in "fluxbox -info"-output
explanation to the changed files:
* xft.m4 -> acinclude.m4 + added ac_path_generic.m4
(from http://ac-archive.sourceforge.net/Miscellaneous/ac_path_generic.html)
* configure.in, Makefile.am, src/FbTk/Makefile.am changed to handle
imlib2-support
* Font.cc/hh Image.cc/hh App.cc fluxbox.cc consistent way of init for global
stuff for fonts and imagehandlers.
* rest of changes just add the imlib2-code, pretty straightforward
