ce5d9de936 [morx] Pass font to format-specific AATLookup.read() methods 
To use self.valueConverter.read(), we will need to pass the font.

191c620951 [morx] Parametrize AATLookup.write() for different value types 2017-08-14 21:34:15 +02:00

61874d3600 [morx] Generalize AATLookup to other value types 
With AAT, the same lookup data structure can be used for various
types of values. In the morx table, the values are glyph IDs or
glyph classes, which both are encoded as 16-bit unsigned integers.
In other AAT tables, however, the values can be different data types
with different encodings. By passing a `valueWriter` callback and
explicit `valueSize`, we prepare for eventually templatizing
the building of AATLookups.

Also, assert that the called writer wrote the exact number of bytes
that was predicted when figuring out what format should be used for
encoding an AATLookup.

bdf29b4169 [morx] Separate building from writing lookup tables 
For AAT lookup format 2 (and other formats too), we need to shuffle
the data before we can estimate the encoded size. After this restructuring,
this data shuffling only needs to happen once.

68dc15375b [morx] Fix output for AATLookup format 6 
We now produce the correct binary search headers, and add a fake item
for terminating the binary search.

b00e2dfec4 [morx] Recognize MorphType as another type of lookup 
Currently, this makes no difference at all. Later, we'll use this
for dispatching AAT lookup types in the same way how we already
dispatch OpenType lookup types.

d89fcf93bc [varLib_test] add 'MVAR' to expected tables list 
Note: the `expect_ttx` test is passing, but the `check_ttx_dump` which ensures the TTX dump is the same after saving and reloading the font, is currently failing, as the "ValueRecordSize" count is None
