b1eeaa5151 [gvar] Fix point encoding 
Where more than one run is used, it's only the first run's first point
that is absolute, all other values are relative.

Similar fix landing in FreeType soon.  Fixes lizzard glyph (glyphname
"dollar") in Zycon.

18b905b06d [ttLib/pyftmerge] Handle cmap merge better (#635) 
Changed the merge algorithm to properly handle cmap subtables
of type 4 and 12 with platform id and encoding ids of 3/1 and 3/10
respectively. All other subtables are not merged and ignored.
The resulting merged cmap table includes a subtable of format 4/3/1
and a format 12 subtable iff there are mappings outside of the BMP.

If one font has two codepoints that point to the same glyph,
and another font has the same code points pointing to two other glyphs,
keep the behavior where the first replacement glyph is stored in 'locl'
and output the third glpyh (or more) to let the user know that they were
dropped, instead of failing to merge the font.

Fixes #444
Fixes #322

5c723ebfb0 [feaLib] Don't assume feature has lookups in DFLT 
It's possible for all of a feature's lookups to be in specific script
and/or language systems, so this code could crash.

e2186dec53 [feaLib] Don't set language when script is unset 
Before, if someone tried to set the language before setting the script
a None/language language system would be created (with actual tag
"None" stored in the feature table). This defaults to tag DFLT and
fails when a non-dflt language is set for DFLT, since that's illegal.

d1af1cfd4a [feaLib] Fix exclude_dflt handling 
This is to fix what I think was a misunderstanding of the exclude_dflt
keyword (and the implicit include_dflt option active by default).

Rather than including the following lookups in the default language
systems, I think it is used to include the lookups specific to default
language systems in the system defined by the current language
statement. Thus instead of registering a lookup in all default
systems when include_dflt is true, we should exclude the lookups
registered with default systems from the current system when
include_dflt is false.

71fb49962a Improve perimeterPen tests 
The tolerance on the pen is set to 0.5%, so it does not make sense
to test for accuracy for anything more than integers given the
values.

Behdad Esfahbod
e53764a16d In calcIntBounds(), round values 
The glyph coordinates in glyf table are going to be rounded when
writing out, so we should use the same mode of conversion to
integers.  Otherwise the xMin of a glyph might end up being
different from its actual minimum X.
