Re: Strange paths from some font sizes

We're getting very strange results from calls to ATSUGlyphGetQuadraticPaths for some sizes of Geneva. Here are the results for the 'c' glyph in 2 sizes. Notice how the 9pt has only linetos, but the 8pt correctly has quadtos. What is causing totally different paths to be generated? The result is that the fonts/sizes that use only linetos look totally wrong, like rough polygons instead of smooth curves. The points listed are all the points sent to our callbacks.

Don't know if this has any relationship to your observations but if I go to SystemPreferences->Appearance and set "Turn off text smoothing for font sizes [6] and smaller" some text in 8 pt Geneva in TextEdit looks fine but if I set text smoothing to 8 then it looks like what you've described.
