=head1 DESCRIPTION
This is a subclass of B<FVWM::Tracker> that enables to read the global
FVWM configuration.
"value changed"
=head1 SYNOPSYS
Using B<FVWM::Module> $module object:
my $config_tracker = $module->track("GlobalConfig");
my $config_hash = $config_tracker->data;
my $image_path = $config_hash->{'ImagePath'};
or:
my $config_tracker = $module->track("GlobalConfig");
my $xinerama_info = $config_tracker->data('XineramaConfig');
my $desktop2_name = $config_tracker->data('DesktopName 2');
=head1 OVERRIDDEN METHODS
=over 4
=item B<data> [I<key>]
Returns either hash ref of all global configuration values, or one value if
I<key> is given.
=item B<dump> [I<key>]
Works similarly to B<data>, but returns debug lines for one or all global
configuration values.
