6cb0a56020 [cffLib] Make sure glyph names are unique
Similar to what we do with “post” table names. I’d have said the font is
broken, but all applications I tried it with loaded it just fine, though
they differed in which glyph to pick from the duplicate ones.

Fixes https://github.com/fonttools/fonttools/issues/1602

ad4bb343fc [cffLib] Support FDSselect format 4
Introduced in CFF2 table, but code does not limit it to CFF2 table. If
FDSelect format is set to 4, it will be read/written regardless of the
table version.

4ee5e6da16 [cffLib specializer] Fix bug in programToCommands with CFF2 charstrings
When checking if there was an initial width argument, old logic did not correctly sum the number of blend and non-blend arguments before the first hint or moveto operator.

Added test case. Old logic dropped the arguments for the hmoveto in the last glyph.

77f72bc62b Convert OTF font files in test data to ttx files.
This required a fix to fontTools/cffLib. When reading a CFF2 variable font (VF) from XML, the VF state in FontDict and PrivateDict does not get set. I made a temporary fix by adding a loop to set PrivateDict.vstore for all the PrivateDict objects after the XML file has been read. This should not be necessary, and in the near future I will revisit both this issue, and the related use of isCFF2 when compiling/decompiling.

Sparse cff2vf support (#1591)
* Added getter (in the form of a property decorator) for T2Charstring.vsindex. Fixes endless compile loop in some circumstances.

Fixed bug in mutator: need to remove vsindex from snapshotted charstrings, plus formatting clean up

* Fix for subsetting HVAR tables that have an AdvanceWidthMap when the --retain-gid option is used. Needed to make subset_test.py::test_retain_gids_cff2 tests pass.

* in varLib/cffLib.py, add support for sparse sources, and sources with more than one model, and hence more than one VarData element in the VarStore.

CFF2 source fonts with multiple FontDicts in the FDArray need some extra work. With sparse fonts, some of the source fonts may have a fewer FontDicts than the default font. The getfd_map function() builds a map from the FontDict indices in the default font to those in each region font. This is needed when building up the blend value lists in the master font FontDict PrivateDicts, in order to fetch PrivateDict values from the correct FontDict in each region font.

In specializer.py, add support for CFF2 CharStrings with blend operators. 1) In generalizeCommands, convert a blend op to a list of args that are blend lists for the following regular operator. A blend list as a default font value, followed by the delta tuple. 2) In specializeCommands(), convert these back to blend ops, combining as many successive blend lists as allowed by the stack limit.

Add test case for sparse CFF2 sources.
The test font has 55 glyphs. 2 glyphs use only 2 sources (weight = 0 and 100). The rest use 4 source fonts: the two end points of the weight axis, and two intermediate masters. The intermediate masters are only 1 design space unit apart, and are used to change glyph design at the point in design space. For the rest, at most 2 glyphs use the same set of source fonts. There are 12 source fonts.

Add test case for specializer programToCommands() and commandsToProgram by converting each CharString.program in the font to a command list, and back again, and comparing original and final versions.
