suzuki toshiya 83c877f11c [mac] Fix ftexport.sym target in Jamfile.
* Jamfile: Update the directories of the header files scanned for
ftexport.sym.  They were incorrect since the migration of the
header files, on 2015-06-22.  Either inexisting include/cache
(removed on 2006-03-20) is not needed to be listed explicitly.
Now ftmac.h is scanned only in the case of Mac OS & Mac OS X.

Alexei Podtelezhnikov 4a2f8f1faf [smooth] Sub-banding protocol revision.
Rasterization sub-banding is utilized at large sizes while using
rather small fixed memory pool. Indeed it is possible to make an
educated guess how much memory is necessary at a given size for a
given glyph. It turns out that, for large majority of European glyphs,
you should store about 8 times more boundary pixels than their height.
Or, vice versa, if your memory pool can hold 800 pixels the band
height should be 100 and you should sub-band anything larger than
that. Should you still run out of memory, FreeType bisects the band
but you have wasted some time. This is what has been implemented in
FreeType since the beginning.

It was overlooked, however, that the top band could grow to twice the
default band size leading to unnecessary memory overflows there. This
commit fixes that. Now the bands are distributed more evenly and
cannot exceed the default size.

Now the magic number 8 is really suitable for rather simple European
scripts. For complex Chinese logograms the magic number should be 13
but that is subject for another day.

* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
protocol.

suzuki toshiya 783cbcd67d [mac] Fix Savannah bug #48417.
Mac OS X linker throws errors when `-exported_symbol_list' input
file includes non-existing symbols.  Reported by Ryan Schmidt.

* builds/exports.mk: Exclude ftmac.h from the headers for apinames
by default.  Include it when ftmac.c would be compiled.

Werner Lemberg 5e353f0786 [autofit] Handle single-point contours as segments.

`NotoSansGurmukhi-Regular' have such isolated points sitting exactly
on other outlines.

ignore one-point contours but handle them specially as one-point
segments.
