This causes a regression in the German computer-aided tax form printing program "Elster-Formular". Previously, font scaling worked like in the GM_COMPATIBLE graphics mode (set via SetGraphicsMode on the DC), that is, mainly abs(yy) is used as scaling factor, and that's it. This change introduces something like the GM_ADVANCED graphics mode, but does it wrong (for example, the origin for reflections should be the point specified in TextOut, currently, reflections are done relative to the base line of the character; also the background is not reflected at all). I have attached a simple test program to show what happens in wine with a scaling that inverts the y axis (as the German tax program uses). Its expected output would be to characters looking the same at the same Y position, which is what I get in windows, and also with Wine 1.0.
If the GM_ADVANCED line is activated, expected output would be the first "F" as is, and the second "F" upside down above the line, with the lowest part of the white box touching the black line. No Wine version does handle this case correctly.
