But this is not the case. You might still be saved by drawing
a horizontal line *after* drawing the extremities though,
but your horizontal line will not be anti-aliased in that case.
On the other hand, when creating a real bitmap, the bitmap
is exported *as is* in the postscript file, which may not be
a very good idea for the Pdf export.
As a general rule, I would like to notice that getting
the characters to match perfectly is quite complicated and very hacky.
However, bad matches are immediately noticed and very ugly...
