I think asking on the pango mailing list ([EMAIL PROTECTED]) is
probably your best bet for this problem. I asked James about this today
and we both agreed that the problem seems to be *rendering* the fonts,
rather than scaling them.
James also pointed out that the XFT backend will be better at rendering
large fonts, since scaled bitmap fonts needed to be completely loaded
into memory before being rendered. To turn on XFT fonts in GTK+ 2.0, use
export GDK_USE_XFT=1
-- it's on by default for 2.2 onwards.

Yes. Both the core font engine and XFT handle TTF fonts correctly
(though you need the freetype module loaded for the former, AFAIK).
However, what you probably want is to *render* fonts using the XFT
backend, which is the hint James provided above.
Take care,
