TypefaceQuery.ObliqueAngle Property
The angle of the slant wanted, in degrees leaning to the right (CSS font-style: oblique 10deg), or null for
the default angle of 14 degrees. It only matters when IsItalic is set: it chooses among faces that declare
an oblique range (the one that holds the angle, or else the nearest), which are preferred to faces declared italic when an angle
is given and the other way round when it is not, and a variable face’s slnt axis is set to it, kept inside the range the
face declares.
