Thanks for pointing this out. A quick addition to the submitted test
case (attached) confirms that win2k does integer scaling. But it does
it in a somewhat inconsistent manner. For instance GetTextExtentPoint32
scales only height but not width, and GetCharWidth does not scale width
either. I'm a bit confused, is that a bug or a feature?
