Re: [css3-mediaqueries] Is 'resolution' in terms of device pixels or CSS pixels?

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
