Only decompose glyphs with reflected components (#171)

Instead of decomposing a component if any scaling is happening, only decompose a component if xScale < 0 or yScale < 0 (that is, if it is mirrored on the x or y axis). Removes yAxisIsNonTrivial which was set for all italic instances and would cause all composed glyphs to be decomposed.

Closes #169
