All types of FeatureParams are correctly handled now.
The only thing not handled is broken fonts generated with the
old AFDKO that have their FeatureParams offset computed wrong.
I don't currently plan on handling those.
Fixes https://github.com/behdad/fonttools/issues/38
Version is really just a major.minor, NOT a Fixed. But it has
been implemented as Fixed. We now:
1. Check that major is 1,
2. If minor is not 0 (only defined for GDEF so far), then
print the whole thing as hex in XML,
3. When reading the XML, accept hex,
4. In all four methods dealing with Version, support both
fixed version (ie. 1.0), and long version (ie. 0x00010000).

# support virtual GIDs, support handling some GSUB offset overflows.

# 1) make getReverseGlyphMap a public function; I find a reverse map
to often be useful
# 2) support virtual glyphs, e.g. references to GID's that are not in the font.
# Added the TTFont argument allowVID (default 0) to turn this off and on;
# added the arg requireReal ( default 0) so as to get the obvious
default behaviour when
# allowVID is 0 or 1, but to allow requiring a true GID when allowVID is 1.

# 1) speed optimization
# - collapse for loops
# - do not decompile extension lookups until a record is requested
from within the lookup.
# 2) handling offset overflows
# 3) support of extension lookups
# 4) Fixed FetauresParam converter class def so as to survive a font
that has this offset non-NULL.
# This fixes a stack dump.
# The data will now just get ignored
