119b7732cc SVG: strip timestamp to make compressed gzip reproducible
we tell GzipFile to write the MTIME field to zero so that the compressed output is reproducible and doesn't change depending on when the data is compressed.

be623e257f Clean up svgDoc compression
This is based on bungeman's https://github.com/fonttools/fonttools/pull/2627

Previously, an entire `SVG ` table would be marked as compressed if any
of the decoded SVG documents in it were compressed. Then on encoding all
SVG documents would be considered for compression. The XML format had no
means to indicate if compression was desired.

Instead, mark each svgDoc with its compression status. When decoding
mark the svgDoc as compressed if the data was compressed. When encoding
try to compress the svgDoc if it is marked as compressed. In the XML
format the data itself is always uncompressed, but allow an optional
`compressed` boolean attribute (defaults to false) to indicate the
svgDoc should be compressed when encoded.

We also try to make sure that older code that relies on docList containing
sequences of three items (doc, startGID, endGID) will continue to work
without modification.

086799357a Enable sharing across subtables of extension for harfbuzz packing.
Harfbuzz repacker can handle subtables shared across extension lookups so there's no need to disallow such sharing. Add a parameter to _doneWriting to allow sharing to be enabled when preparing the object graph for passing to harfbuzz.

795bccd966 TTFont: load all on open w/ lazy=False; add ensureDecompiled
Make lazy=False actually do what it says, 'load everything eagerly'. It feels weird that one has to, not only say, open with lazy=False, but also have to load each tables individually... Didn't I say don't be lazy?!

Also it can be useful to get to a eager, non-lazy font whether or not it was originally loaded lazily, so I added an ensureDecompiled method that decompiles all the tables and calls ensureDecompiled for those (e.g. cmap, glyf and otData-driven tables like GSUB, GPOS, etc.) that respect the lazy attribute.
