MultiResolutionImageSupport optimizations:

- ProducerMultiResolutionImage: avoid creation of base image to get image width and height, because if screen is scaled then the base image would be never painted, but consumes memory and takes time to create it
- MappedMultiResolutionImage: delegate getting width/height/source/property to original image, to defer/avoid creation of mapped image
