This + commit #ifdefs out the check so PostScript interpreters using + FreeType can render these files. + + The specification says `setcurrentpoint' should only be used to set + the point after a `Subr' call, but these fonts use it to set the + initial point to (0,0).

However, this value + is defined in the PDF and PostScript specs, and that algorithm is + better than the one FreeType currently uses: + + FreeType: Use the middle of the bounding box as the X coordinate + of the vertical origin. + + Adobe PDF spec: Use the middle of the horizontal advance vector as + the X coordinate of the vertical origin. + + FreeType's algorithm goes wrong if you have a really small glyph + (like the full-width, circle-like dot at the end of the sentence, as + used in CJK scripts) with large bearings. With the FreeType + algorithm this dot gets centered on the baseline; with the PDF + algorithm it gets the correct location (in the top right). Note + that this is a serious issue, it's like printing the dot at the end + of a Roman sentence at the center of the textline instead of on the + baseline like it should. So i believe the PDF spec's algorithm + should be used in FreeType as well. + + The `vertBearingY' value for such small glyphs is also very strange + if no `vmtx' information is present, since the height of the bbox is + not representable for the height of the glyph visually (the + whitespace up to the baseline is part of the glyph). The fix also + includes some code for a better estimate of `vertBearingY'. + + * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' + is now calculated as described by the Adobe PDF Spec.

However, there are fonts like `pala.ttf' + which additionally contain this instruction in the hinting code of + some glyphs (but not all). As a result it can happen that a + composite glyph needs multiple drop-out modes for its subglyphs + since the rendering state gets reset for each subglyph. + + FreeType collects the hinted outlines from all subglyphs, then it + sends the data to the rasterizer. It also sends the drop-out mode + -- after hinting has been applied -- and here is the error: It sends + the drop-out mode of the last subglyph only; drop-out modes of all + other subglyphs are lost. + + This patch fixes the problem; it adds a second, alternative + mechanism to pass the drop-out mode: For each contour, the + rasterizer now checks the first `tags' array element.
