IfcFontStyle

Definition from CSS1 (W3C Recommendation): The font-style property selects between normal (sometimes referred to as "roman" or "upright"), italic and oblique faces within a font family. Values are:

- normal
- italic
- oblique

A value of 'normal' selects a font that is classified as 'normal' in the user agents font database, while 'oblique' selects a font that is labeled 'oblique'. A value of 'italic' selects a font that is labeled 'italic', or, if that is not available, one labeled 'oblique'. The font that is labeled 'oblique' in the user agents font database may actually have been generated by electronically slanting a normal font.

Fonts with Oblique, Slanted or Incline in their names will typically be labeled 'oblique' in the user agents font database. Fonts with Italic, Cursive or Kursiv in their names will typically be labeled 'italic'.
