ReadCSSRules: is the front-end function called by the HTML parser
when detecting a <STYLE TYPE="text/css"> indicating it's the
beginning of a CSS fragment or when reading a file .css.
The CSS parser has to handle <!-- ... --> constructs used to
prevent prehistoric browser from displaying the CSS as a text
content. It will stop on any sequence "<x" where x is different
from ! and will return x as to the caller. Theorically x should
be equal to / for the </STYLE> end of style.
The parameter doc gives the document tree that contains CSS information.
The parameter docRef gives the document to which CSS are to be applied.
This function uses the current css context or creates it. It's able
to work on the given buffer or call GetNextChar to read the parsed
file.
Parameter withUndo indicates whether the changes made in the document
structure and content have to be registered in the Undo queue or not
