%%% Enhance support for image inclusion
%
% Resize images that are too large (in width or height).
% Pandoc already includes a similar hack for the width,
% but images can also be too heigh.
%
% Depending on the beamer template used and the resulting
% available space, you might want to adjust the target
% maximum height (here: 0.65, which is 65% of the frame
% height) to another value. Remember headline, footline
% and titles may need additional space.
