I have never known about this font -- very stylistic indeed. :)

While there are plenty of strokes that go well above the cap height or 
below the baseline, the Win Ascent and Win Descent values (which are 
defined as yMax for all glyphs and -yMin for all glyphs, respectively) 
in the metric tables are valid - none of the glyphs violate these 
limits, so the patch doesn't affect this (correctly-formatted) font.

I loaded it up in Wine's Notepad, both with and without my patch, and 
took screenshots of the output:

I even did a pixel-by-pixel comparison: they render the same!

Sadly I can't make any comparisons to how Windows would handle the font. 
My Win XP VM complains about the ttf being corrupt. Is there a similar 
font that will work on Windows that I could try?

Thanks,
Sam
