Log Message:
-----------
[subpixel] MathOperator::paint should snap paint location to device pixel
https://bugs.webkit.org/show_bug.cgi?id=304494
Reviewed by Antti Koivisto.
This is similar to what we do in TextBoxPainter (currently should have no
effect as
coordinates are all integral (except MathML renderers selectively keep
fractional values).
This is also in preparation for enabling subpixel inline layout.)

These tests pass with Monospace font and with Ahem the 0.03px delta turns into
a whole pixel -> add more tolerance.
