Sorry, I forgot: GCPM uses <dpi>, but not 'dpcm' for its |image-
resolution| property <http://www.w3.org/TR/css3-gcpm/#image>, and
would have to be changed accordingly.
Note that 'pt' may be a substitute for 'in', when using the reciprocal.
72dpi => 1pt ~= 0.353mm
96dpi => 0.75pt ~= 0.265mm
300dpi => 0.24pt ~= 0.085mm
