static bool	ReportProgress (void *handle, float progress)
	Report running progress Returns true if handling function was invoked Method can be used to detect if there any progress handler assigned.

static bool	SetClassDrawOption (const ClassArg &, const std::string &)
	Set draw option for the class Return true if entry for the class exists.
