instancer: enumerate fvar axis indices only once then look them up 
fvar axis tags are unique, we can compute the mapping from tag to index
once and reuse when we need them index from the tag.

instancer: unpack axis (start, peak, end) tuple instead of indexing at PEAK_COORD_INDEX 
Makes it more readable

instancer: round MVAR deltas at the end 
and don't use enumerate() when iterating over region axes, as get_support() method returns a dict

62c98b451a instancer: share same instantiateTupleVariationStore for both gvar/cvar 
refactored code, hopefully simplifying things a bit.

for cvar/cvt we do the rounding only at the end after we have summed the scaled deltas
to avoid introducing unnecessary rounding errors.

1fe0348bad Remove old debug pdb.set_trace(). This has already been fixed on another branch that has not yet been merged, but I need to fix it here for the VVAR test to pass. 2019-03-21 10:48:56 -07:00

355139db5a let input axis_limits be a map axis_tag:value as well as range tuples 
this way instanceVariableFont function can be used as drop-in replacement for
mutator.instaceVariableFont (which only accepts single-point locations, not ranges)

df3bbbb7ad varLib: use hhea.ascent and head.unitsPerEM for phantom pts when vmtx missing

52ec934a02 varLib: use vmtx to compute phantom pts; fix sign of bottomSideY 
when 'vmtx' is present in a font, use that to compute the third and fourth 'phantom points'.
When not present, we use the glyph bbox yMax and yMin coords.

NOTE that previously the bottomSideY was incorrectly set to -glyph.yMin (with a minus sign).
However, the minus is not needed when we use the bbox.
Positive vertical advance grows towards negative Y axis.

Revert "load_masters: actually assign font attributes" (#1486) 
* Revert "load_masters: actually assign font attributes"

This reverts commit ef1d4cd02d1e46f5dac3914f547a6e4275cf3077, which caused a
crash in `interpolate_layout()` when `deepcopy`ing OTFs.

Amend code and tests while I work on a real fix.

[varLib] allow loading masters from TTX files as well 
in a designspace document, the sources' filename attribute can now contain
a relative path to a .TTX file for that master, in addition to .TTF or .UFO
(the latter, resolved through a master_finder callable as before).

varLib: use addMultilingualName method to support localized axes 'labelname' 
now that addMultilingualName method also adds mac names by default, we can use it in
varLib instead of addName.
The language identifiers are expected to be minimized, i.e. not contain default script/region
subtags -- until we implement the minimizeSubtags algorithm from ICU/CLDR:
