+
+ [ftstroke] Major revision.
+
+ The main problems
+ -----------------
+
+ o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
+ joins (not bevel joins) were generated. Indeed, the meanings of
+ `miter' and `bevel' were incorrectly reversed (consistently) in
+ both the code and comments.
+
+ o The way bevel joins were constructed (whether specified
+ explicitly, or created as a result of exceeding the miter limit)
+ did not match what is required for stroked text in PostScript or
+ PDF.
+
+ The main fixes
+ --------------
+
+ o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
+
+ o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
+ introduced to support PostScript and PDF miter joins.
+
+ o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
+ alias for FT_STROKER_LINEJOIN_MITER.
+
+ Additionally, a variety of stroking errors have been fixed. These
+ would cause various artifacts (including points `at infinity'),
+ especially when stroking poor quality fonts.
+
+ See
+
+ http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
+
+ for example documents. The FreeType stroker now produces results
+ very similar to that produced by GhostScript and Distiller for these
+ fonts.
+
+ Other problems
+ --------------
+
+ The following problems have been resolved:
+
+ o Inside corners could be generated incorrectly. Intersecting the
+ inside corner could cause a missing triangular area and other
+ effects.
+
+ The intersection point can only be used if the join is between
+ two lines and both lines are long enough. The `optimization'
+ condition in `ft_stroker_inside' has been corrected; this
+ requires the line length to be passed into various functions and
+ stored in `FT_StrokerRec'.
+
+ o Incorrect cubic curves could be generated. The angle
+ calculations in `FT_Stroker_CubicTo' have been corrected to
+ handle the case of the curve crossing the +/-PI direction.
+
+ o If the border radius was greater than the radius of curvature of
+ a curve, then the negative sector would end up outside (not
+ inside) the border. This situation is now recognized and the
+ negative sector is circumnavigated in the opposite direction.
+ (If round line joins are being used, this code is disabled
+ because the line join will always cover the negative sector.)
+
+ o When a curve is split, the arcs may not join smoothly (especially
+ if the curve turns sharply back on itself). Changes in
+ direction between adjacent arcs were not handled. A round
+ corner is now added if the deviation from one arc to the next is
+ greater than a suitable threshold.
+
+ o The current direction wasn't retained if a the outline contained
+ a zero length lineto or a curve that was determined to be
+ `basically a point'. This could cause a spurious join to be
+ added.
+
+ o Cubics with close control points could be mishandled. All eight
+ cases are now distinguished correctly.
+
+ Other improvements
+ ------------------
+
+ o Borders for cubic curves could be too `flat'.
+ FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
+ this.
+
+ o The handling and use of movable points has been simplified a
+ little.
+
+ o Various values are now computed only if the results are actually
+ needed.
+
+ o The directions of the outer and inner borders have been swapped,
+ as recommended by Graham Asher.
