On macOS, `GlyphMetrics` advance provides only the x-component of the advance, not the y-component. This is usually not an issue, since most text does not have any y-component advance. However, if the font is rotated, this does cause problems.
This bug was discovered during fixing of the manual test `java/awt/print/PrinterJob/PrintTextTest.java` (this test is intended to test printing, but this bug was actually causing the `GlyphVector`s on page 8 to be drawn incorrectly on screen, not just on paper). `FileFontStrike.getGlyphMetrics( )` was helpful as a guide regarding the expected behavior of `CStrike.getGlyphMetrics( )`.
