Yes (at least from an "as the artist seems to have intended"
standpoint). I can try to get in touch with Primoz Peterlin (maintainer
of the FreeFont package) and see if it is truly as he intended or see if
he'd be willing to change it for his next release.

This isn't so much true. With Bitstream Vera, you'd get height values
similar to the old FreeSans height. It seems to also ignore
superscript/subscript placement when providing a font-level height value.

Replacing FreeFont fonts with another license-compatible font may be the
"easiest" fix that doesn't involve custom font modifications. I don't
know how the Bitstream Vera license would mix with Myth's GPL, though,
and don't know of any GPL'ed fonts other than FreeFont, so this may not

That may be why most people who seem to encounter similar issues on the
'net seem to resort to switching to aggdraw.

That would definitely be a very font-dependent design, so I agree it's

That's easy to do with FreeType. PIL just doesn't seem to have made the
glyph height available to Python, yet. If you have any ideas for how we
could get from FreeType to Python, I might be able to help.
Also, Myth has support for FreeType for the OSD's, etc., so I don't know
if it would be possible to make some interface between the Python and
C++ code (I think PIL also has some support for QT pixmap format, but
perhaps only in the newest version or so). This may also have the
advantage of allowing for reuse of the fonts/glyphs through Gregg's
up-and-coming generic cache. (But I have to admit I know nothing about
the ease of interfacing the two.)
