This reverts commit edecdce0a576b2e15e21711bcc73ae9beba0c527.

Was wrong.  Will figure out the correct version.

7d5fbe1605 [varLib.featureVars] Improve new algorithm to its full potential 
See 0283b1f.

By finishing overlayBox() to cull remainder box when possible, we generate
far fewer spurious boxes, if any.

For the featureVars_test.py test case, this now generates optimal output,
that is, 2*n - 1 boxes.

Running time for n=20 stays at 0.06s, which is probably Python startup
time.

Running time for n=100 is down from 2.5s with unoptimized new algorithm,
to 0.17s for this and number of output boxes from 5050 to the optimal 199.

Fixes #1372 again

0be1636176 [varLib.featureVars] Optimize popCount() 
While might look like unjustified micro-optimizing, for featureVars_test.py with
n=100, speeds up 10%.  From 2.5s to 2.2s.

0283b1fd1d [varLib.featureVars] Rewrite algorithm 
Whereas previous algorithm had exponential running time and return
value size, new one has quadratic.

For featureVars_test.py test case, for example, which is a pathological
test case of n sliding intervals, the number of output intervals of
various algorithms are:

- Previous algorithm: 2**n - 1
- New algorithm: n*(n-1)/2
- Optimal algorithm: 2*n - 1

Ie, we go from exponential to quadratic, whereas in this case the optimal
solution is linear.

Running time of said test, for n=20, goes from over 20s, to 0.06s.

The algorithm can be improved.  The overlayBox() function currently does
not try to shrink the remainder box.  Doing that will probably bring us
to optimal solution for this test case.

Fixes https://github.com/fonttools/fonttools/pull/1372

One test is failing.  Needs to be investigated that new output is correct,
and test expectations updated.

50dae4cc90 subset: don't error if STAT has no AxisValue tables 
the minimalist STAT table that varLib produces only contains one DesignAxisRecord
for each fvar axis, and has AxisValueCount=0, thus the AxisValueArray offset is None.

transform: add getters for xScale, xyScale, yxScale, yScale, xOffset and yOffset 
UFO images have a transformation matrix with those names.
This makes the Transform look more like a namedtuple, in that it can be accessed both by

7ee81c8821 [varLib] Take total bounding box into account when resolving model 
Umm. Not sure how useful this is, but helps with cases where there
were not masters on extremes and people expected this to work.
Happens in Higher-Order Interpolation since the axis extremes
are not interesting.
