    Output .glade files saved in Windows containing Pixbuf widgets with relative paths to image files e.g. 
ui_graphics/background.png were changed from forward-slash (/) to backslash (\) due to use of GTK macro. E.g. 
ui_graphics\background.png Then, when the Glade file was loaded in Linux, the Pixbuf widget relative path did 
not work anymore b/c backslash (\) was not understood. Forward slashes (/) are always understood, so changed 
always use forward slashes.
