% Macros converting foils.cls into CMP slides (screens supported talks)
% (c) Vit Zyka
% 1999-11-30 : first version created in Ljubjana
% 2000-04-05 : correction of \shref in \cmpiistyle
% 2000-05-09 : rename of \linethickness to \talklinethickness
% 2000-05-18 : \long for \shyperlink and \shref
%              \maskfoil for not presented slide in main course
% 2000-12-02 : \itemize with plus?ex glue
% 2000-12-06 : remove final \vfill in \@foilhead (conflict with texpower)
%              frame rule by cmprulecolor (default by black)
%              slidetitle set to \appendixname
% 2001-05-11 : when using TeXPower package make text color black
% 2001-05-23 : arpgcell included (two column for page numbers)
% 2001-10-06 : \enumerate with plus?ex glue
% 2001-10-16 : CAKi style, cmpiistyle cleaning
% 2001-10-17 : \sideImgAB
% 2001-12-03 : v1.9; correction of package loading, CAKorange color
%              noloadhyperref, noloadgraphicx
%              corrections in hyperlinks: \@pdfborder, no highlight
%
% To do:
% - background color
% - simple style without page numbers -- only 4/9 (Pajdla)
% - mouse control: Prev/Next Page
% - empty page switch
