The following is a redesign that extends the class internally. The main goal is to preserve the characteristics of the pImpl idiom for data encapsulation, while simultaneously reducing the memory allocation overhead typically associated with pImpl. The stragegy is here: Rather than alloc the impl memory inside of the thorvg engine, impl extends the API classes in order to consolidate the memory. size has been decreased by -4kb with optimization=s issue: https://github.com/thorvg/thorvg/issues/3214
