 // Class that evaluates css media queries as defined in
 // CSS3 Module "Media Queries" (http://www.w3.org/TR/css3-mediaqueries/)
 // Special constructors are needed, if simple media queries are to be
 // evaluated without knowledge of the medium features. This can happen
 // for example when parsing UA stylesheets, if evaluation is done
 // right after parsing.
 //
 // the boolean parameter is used to approximate results of evaluation, if
 // the device characteristics are not known. This can be used to prune the loading
 // of stylesheets to only those which are probable to match.
