Rounding of coordinates is now disabled by default.
The pen now accepts an optional 'roundTolerance' float, with values between
0 and 1 (default is 0).
Values >= 0.5 mean round all coordinates to integers.
Values between 0 and 0.5 mean round only when the absolute difference
between the original float and the rounded integer is within the tolerance

* [feaLib.ast] fix checking multiple markClass definitions don't redefine same glyphs
As pointed out by @mhosken, we are looking in the wrong list for glyphs
that have already been defined in a previous markClass definition.
With this patch, the current markClass.fea test case fails becuase it defines 'acute'
twice for the same @TOP_MARKS class:
fontTools.feaLib.error.FeatureLibError: Lib/fontTools/feaLib/testdata/markClass.fea:6:5: Glyph acute already defined at Lib/fontTools/feaLib/testdata/markClass.fea:3:1
Also see conversation at:
3b79d51755 (r94622074)
* feaLib/testdat/markClass.fea: remove duplicate 'acute' in @TOP_MARKS
Now the test pass, after 45c77b7
* [feaLib.builder_test] test case for redefined glyph in multiple markClass definitions
This should be a bit more efficient as we don't need to create a temporary list
object before passing it to "".join() method of str; the latter accepts any
Iterable
The convention is that sys.exit(...) is called only if a module is run as a script,
and that main() entry points use return statements to report exit codes: 0 (or None)
for successful execution, or any non-zero integer for errors.
E.g. see the console scripts generated when installing with pip.
If a module is run as script, as in `python module.py` or when using
`runpy.run_module()`, then __name__ == "__main__".
So when we instantiate modules' loggers with `logging.getLogger(__name__)`,
those loggers' name may become "__main__" when run as scripts, and hence
fall outside of the "fontTools" logging namespace.
fontTools.configureLogger() by default only configures the "fontTools"
library loggers, anything outside of it (e.g. logger called "__main__")
is not attached a handler.
So here I name loggers explicitly instead of relying on __name__, but
only for modules which can be run as "__main__".

Although for the XML->binary case, that bug was already fixed
on master because of the XML populate-default changes.
This adds extra protection!
