/** This class manages a font.
|
|
The idea is to create a FontInfo object with a font name pattern with a
|
|
wildcard at the size field. Then this object can host request for font-
|
|
instances of any given size. If no exact match is found, the closest size
|
|
is chosen instead. If the font is scalable, the flag
|
|
lyxrc.use_scalable_fonts determines whether to allow scalable fonts to
|
|
give an exact match.
