% ChangeLog:
% 1.12 - bugfixed fontscale/myfontscale indention calculation
%      - added beamerposterarticle icon format
% 1.11 - removed incompatible paralist package, used beamer's leftmargin lengths instead for indention
% 1.10 - improved PackageWarning and PackageInfo outputs
% 1.09 - bugfixed the list indention problem, can be overwritten by user with the \setdefaultleftmargin command.
%      - added 'printer' option for external printer definition files
% 1.08 - supports external printer definition files
%      - added grid mode option
%      - renamed beamer specific variables
%      - added font size normalization, so that scale=1.0 is the default font size for all DIN-A(n) sizes
% 1.07 - bugfixed custom size handling, portrait or landscape settings are ignored now
% 1.06 - added the type1cm package for scalable math fonts
% 1.05 - added version check for xkeyval package
% 1.04 - added custom size handling
% 1.03 - improved predefined size handling
% 1.02 - minor bugfixes
% 1.01 - bugfixed size handling
% 1.00 - first beamerposter release
