Thanks – that is
certainly useful information. But I must stress that it is unlikely that I will
find very much time to look into this. Yes, I do feel guilty.
Best regards,
Graham

hinting when vertical and horizontal point sizes are different
Hi Graham,
I've found something pertinent to this problem. When you use
FT_Set_Transform with a rotation matrix like for 90, 180, or 270 degrees the
rendering is messed up and example follows. Zero degrees rotation looks
great for "Arial.ttf".
Letter O like in Oreo at 20pts tall and 10pts wide at 203dpi rotated is a blob
at zero degrees it looks great.
Letter O(reo)

I shall try to look at it - coincidentally, I am doing some FreeType work
right now - but it is hard for me to make a commitment to fix this by a
certain date.

Graham, can you have a look at it?
