<![CDATA[LSB miscalculated in TTF export]]>The LSB value in the hmtx table is miscalculated when exporting TTFs which have off-curve points as the leftmost point ...

See attached example TTF, both glyphs, /A and /a, have a LSB of 30 in the hmtx table, but for /a it should be about 13.

This causes the outlines in the exported TTFs to shift noticeably to the right.

its seems to be a fontTools issue :)

http://sourceforge.net/p/fonttools/code/ci/master/tree/Lib/fontTools/ttLib/tables/_g_l_y_f.py#l549

it seems to recalculate the bounds from all points instead of analysing the bounds of the contour

(this will be fixed in the next version...
