Be able to parse numbers with no digits before the decimal point.

Per the [SVG spec](http://www.w3.org/TR/SVG11/types.html#DataTypeNumber), non-integer number values do not necessarily have any digits before the decimal point.
Be able to parse viewbox numbers with no digits before the decimal.
Update unit tests to use degrees for imported SVG rotations.
Add test for parsing numbers with no digits before the decimal point.
Use a cubic bezier approximation for rounded rectangle corners.

According to the SVG spec these corners are supposed to be elliptical arcs.  HTML canvas does not have methods for elliptical arcs, but a cubic approximation can get within 0.02%.

Using the "magic number" from http://itc.ktu.lt/itc354/Riskus354.pdf.
