Fixed font attribute inheritence, text and textArea elements in QtSvg.
Text used to be formatted during the parsing of the SVG file, but
because the text can be referenced by a 'use' element, the text
formatting is not known at this point in time. Now, font attributes can
be inherited from 'use' elements, and the text is formatted each time
it is drawn.
