The text layout code passes a boolean flag down to the
native layer which is used to inform it how to handle device scales.
For sun.font.TrueType instances this is a cheap test, but
since on MacOS the CFont class is used, the call is very expensive
on Mac, since it makes a native call which uses core text to
retrieve the table and constructs a Java byte array and passes
it up to Java. All to discover the layout technology of the font.
If this can't be made much cheaper, the result should be cached.
