In systems with bamfdaemon running, windows get this property for
finding the dekstop spec file of an application. This can be used to
find the defined icon for any application window that reports this
attribute and provider much better icon matching.

Looking up GDesktopAppInfo from the GTK Application ID we can get a much
better match for the icon and load it at the appropriate scale. This
results in matching icons to straneous windows and better looking icons
overall.

Some files do not report their application icons correctly in the window
properties. This patch allows the marco UI to search for the
corresponding .desktop file and render the icon in the desktop info on
both the alt-tab popup and the window mini-icon.

find . \( -name '*.h' -o -name '*.c' \) -exec sed -i 'N;/^\n$/D;P;D;' {} \;

Just run:
 $ find -name '*.c' -print0 | xargs -r0 sed -e 's/[[:blank:]]\+$//' -i
 $ find -name '*.h' -print0 | xargs -r0 sed -e 's/[[:blank:]]\+$//' -i
