Setting polygonMode should use FRONT_AND_BACK when possible #43

Separate polygon modes are deprecated nowadays (see e.g. section D.2 of the OpenGL 4.3 spec), so polygonMode should handle this properly: When the given PolygonModes are equal, use FRONT_AND_BACK, otherwise separate FRONT and BACK calls. This way we can keep the signature of polygonMode and use non-deprecated functionality when possible.
