These flags indicate how the font is to be used. They affect presentation
speed and font quality.
FATTR_FONTUSE_NOMIX
Text is not mixed with graphics
and can be written without regard to any interaction with graphics objects.
FATTR_FONTUSE_OUTLINE
Select
an outline (vector) font. The font characters can be used as part of a path
definition. If this flag is not set, an outline font might or might not
be selected. If an outline font is selected, however, character widths are
rounded to an integral number of pels.
FATTR_FONTUSE_TRANSFORMABLE
Characters can be transformed (for example, scaled,
rotated, or sheared).
