Method supportsRenderScale

Engine/EffectInstance.cpp:3161–3170

* @brief Does this effect supports rendering at a different scale than 1 ? * There is no OFX property for this purpose. The only solution found for OFX is that if a isIdentity * with renderscale != 1 fails, the host retries with renderscale = 1 (and upscaled images). * If the renderScale support was not set, this throws an exception. **/

 * If the renderScale support was not set, this throws an exception.
