fontVariations() does not work correctly on Linux

[Just van Rossum]

Possibly due to a bug in skia-python: kyamagu/skia-python/issues/112

Or due to me using the skia-python API wrong.

This test script does not give the expected result on Linux: https://github.com/justvanrossum/drawbot-skia/blob/master/tests/apitests/fontVariations.py

This appears to be fixed thanks to recent changes to the TextStyle object: I no longer use the skia API to get at the current VF location, and setting is apparently not a problem.
