+% slide, don't know yet)

+% footline definitions
+% 
+% The footline is one of the things that are heavily customizable in beamer using
+% outer themes. However, we skip (and do not support) all those fancy beamer 
+% themes here and just let beamer it render as text line. This gives us full 
+% control and easy adaptation, but some things (especially the vertical layout)
+% remain a bit hacky :-)
+%
+% To provide for more easy customization within presentations, the framenumbering
+% can be customized (and also locally surpressed) by overwriting the 
+% macro \InsertFrameNumber
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+  % default style for frame numbers 
+  \def\InsertFrameNumber{\insertframenumber\,--\,\inserttotalframenumber}

+      % insert a strut (invisible vertical line) to prevent line breaks
+      \rule{0mm}{3mm}

+% frametitle setup 
+% 
+% This is probably the most hacky part of i4beamer We completely overwrite the  
+% code beamer uses to render the frame title, especially to get the vertical
+% spacing and alignment right, so it fits with the "background".
+%
+% The i4-Layout does not really offer space for subtitles. We support them 
+% anyway by printing them right-aligned.
