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).

However, there are fonts like `pala.ttf' + which additionally contain this instruction in the hinting code of + some glyphs (but not all).
