This commit introduces new counters and deprecation warnings for the following MathML features: * mathspace names (bug 1575542) * mathsize names (bug 1548527) * linethickness names (bug 1548529) Note: helper parsing functions for mfrac and mpadded are changed to non-static in order to pass the document parameter needed to log warnings to the console. Change manually tested with <math> <mspace width="thinmathspace"></mspace> <mpadded width="2thickmathspace"></mpadded> <mfrac linethickness="thin"><mn>1</mn><mn>2</mn></mfrac> <mtext mathsize="big">3</mtext> </math> Differential Revision: https://phabricator.services.mozilla.com/D42890 --HG-- extra : moz-landing-system : lando
