In Quartz, the "graphics port" bound to an NSGraphicsContext (subclassed by OpalContext) is a CGContext. We currently initialize one in OpalSurface if it does not exist, however we do not allow the client to initialize a graphics context with a custom graphics port, which should be allowed. This commit enables this feature.
