Unlike simple glyphs, which always have 'program' attribute (even when empty, with no instructions)
in composite glyphs, it's the presence of 'program' attribute that determines whether
the optional WE_HAVE_INSTRUCTIONS component flag is set or not.
Thus, the trim method (with remove_hinting=True) should delete the attribute for
composite glyphs.

otherwise one gets AttributeError: 'module' object has no attribute 'block'
I noticed this by change. The whole SIL lz4-compressed Glif/Silf tables is still untested...
so that's comparable/hashable/immutable and can be used as key in a dict or set.
The fromXML instance method was dropped since it relied on the object being mutable.
A fromHex classmethod replaces it.
when no horizontal/vertical header table is present, we assume numberOfHMetrics == maxp.numGlyphs.
This allows to compile/decompile incomplete fonts, only containing head, maxp, hmtx, loca and glyf (or CFF),
that is the bare minimum to temporarily store glyph outline and metrics data for use with sparse/intermediate
master TTFs in varLib.

* cleanup cmap format 14 TTX format by removing redundant attributes
* don't output the name attr for a default mapping, instead of a glyph named 'None'
* still accept 'None' as an indicator glyph name, for bw compatibility
* swap order of TTX attrs uv and uvs
* make sure (unicode, glyphName) pairs are always tuples in uvsDict.
on py27, calling deepcopy on a file object doesn't raise TypeError, but leaves
the duplicated file object in an inconsistent state:
https://travis-ci.org/fonttools/fonttools/jobs/474811063#L714
any operations on it will fail with 'ValueError: I/O operation on uninitialized object'.
Thus, for semplicity for now we always do a manual copy the file contents into an
in-memory BytesIO stream, rather than attempting to call deepcopy first.
when ttx fails to decompile a buggy glyf table, the DefaultTable implementation is used,
but TTFont._tableToXML passes 'splitGlyphs' keyword argument to table.toXML when
the tag is 'glyf'.
Let's simply ignore it here.
* Implement glyf outline flags bit 6 when decompiling/compiling
* Add test data for outline flag bit 6
* Rename flags, use bitwise OR for setting flag bit
* Remove unneeded code
