It's rather unused. Changing it on the font pattern wouldn't affect rendering. Changing it on the query pattern kinda works (if size is specified, not pixelsize). I suggest we deprecate it completely. FC_MATRIX has been used for scaling when needed.
that sounds good to me. let's make it deprecated then.
Fixed in git 55ff841
