This ensured that the path was closed (in both + Character Space and Device Space). But if the final element was a + curve and if the final hintmap was different enough from the initial + one, then the curve was visibly distorted. + + The first part of the fix is to draw the final curve using the final + hintmap as specified by the charstring. This corrects the + distortion but does not ensure closing in Device Space. It may + require the rasterizer to automatically generate an extra closing + line. Depending on the hintmap differences, this line could be from + zero to a couple pixels in length. + + The second part of the fix covers the case where the charstring + subpath is closed with an explicit line. We now modify that line's + end point to avoid the distortion. + + Some glyphs in the bug report font (TexGyreHeros-Regular) that show + the change are: + + 25ppem S (98) + 24ppem eight (52) + 25.5ppem p (85) + + Curves at the *end* of a subpath are no longer distorted. However, + some of these glyphs have bad hint substitutions in the middle of a + subpath, and these are not affected. + + The patch has been tested with a set of 106 fonts that shipped with + Adobe Creative Suite 4, together with 756 Open Source CFF fonts from + Google Fonts. There are 1.5 million glyphs, of which some 20k are + changed with the fix.
