Based on Miguel Sousa's original PR and the following discussion: https://github.com/googlei18n/cu2qu/pull/114 Instead of raising an error at the first incompatible glyph, we let it continue (keeping the original contours unmodified when that happens), and use logging to print error messages. A new `IncompatibleFontsError` exception is raised at the end of `fonts_to_quadratic` if any glyph has incompatible number or types of segments. The exception instance has a `glyph_errors` attribute (dict) which collects all the individual IncompatibleGlyphsError keyed by glyph name.
