*
* FT_STROKER_LINEJOIN_BEVEL ::
* Used to render beveled line joins; i.e., the two joining lines
* are extended until they intersect.
* Used to render beveled line joins. The outer corner of
* the joined lines is filled by enclosing the triangular
* region of the corner with a straight line between the
* outer corners of each stroke.
*
* FT_STROKER_LINEJOIN_MITER_FIXED ::
* Used to render mitered line joins, with fixed bevels if the
* miter limit is exceeded. The outer edges of the strokes
* for the two segments are extended until they meet at an
* angle. If the segments meet at too sharp an angle (such
* that the miter would extend from the intersection of the
* segments a distance greater than the product of the miter
* limit value and the border radius), then a bevel join (see
* above) is used instead. This prevents long spikes being
* created. FT_STROKER_LINEJOIN_MITER_FIXED generates a miter
* line join as used in PostScript and PDF.
*
* FT_STROKER_LINEJOIN_MITER_VARIABLE ::
* FT_STROKER_LINEJOIN_MITER ::
* Same as beveled rendering, except that an additional line
* break is added if the angle between the two joining lines
* is too closed (this is useful to avoid unpleasant spikes
* in beveled rendering).
* Used to render mitered line joins, with variable bevels if
* the miter limit is exceeded. The intersection of the
* strokes is clipped at a line perpendicular to the bisector
* of the angle between the strokes, at the distance from the
* intersection of the segments equal to the product of the
* miter limit value and the border radius. This prevents
* long spikes being created.
* FT_STROKER_LINEJOIN_MITER_VARIABLE generates a mitered line
* join as used in XPS. FT_STROKER_LINEJOIN_MITER is an alias
* for FT_STROKER_LINEJOIN_MITER_VARIABLE, retained for
* backwards compatibility.
