I have no idea why the commit is "mknauer authored", that was not the case.

It's better to implement it in PropertyResolver.readFontSize(LexicalUnit) instead of PropertyResolver.readSingleLengthUnit. PropertyResolver.readSingleLengthUnit is used in other places like readDimension or readShadow, where pt does not make sense. Please add a test to org.eclipse.rap.rwt.internal.theme.css.PropertyResolver_Test.testFontSize().
