Yes, I disabled embed-bitmap support in fontconfig, and only tested the
OUTLINE glyphs of "Sazanami mincho".
I also found problems with some old PCF/BDF Chinese fonts, for example,
"Song" and "FangSong" shiped with Xorg.
If I use such a font, the auto-matched Chinese pixelsize is even bigger
than 2 * monospace width.:-(
By the way, some korean PCF fonts also had this problem.
At first, I disable pcf/bdf support in this patch, If it is a pcf/bdf
font, just keep it unchanged.
but this is really not a good idea. for example, "SimSun.ttc"(the
default font of Windowz XP CN version) is a very famous font for
Chinese, almost everyone use it, it provides 9/10/11pt embedded bitmap
"song". A lot of users even can not accept "ClearType" and "YaHei" in
Vizta and Win 7. :-D

Yes, I agree, We should try best to keep everything work well.
I consider to ignore PCF/BDF font again in this patch.
