This adds an 'axis' child element to the 'font' element. The 'axis' element has attributes 'tag' (a four byte identifier) and 'stylevalue' (a float value) to the parser. This also modifies reading the font file name in a backwards compatible fashion by using only the direct #text children of the 'font' element. (Both the Minikin and Skia parsers now allow the font file name on a separate line in the fonts.xml file). This information is then passed through to Skia in order to select the desired variation. The Skia parser already parses this way and has for some time, so Chrome and WebView can already read this format.
