Reviewed by Tim Nguyen.

The RoundTile and SpaceTile didn't take the scale factors computed in NinePieceImage,
so would arrive at incorrect counts. This caused the logic to scale images when it
should have left them unscaled, and simply tiled (or spaced) the elements.

This change progresses four WPT tests:
(1) border-image-repeat-round.html
(2) border-image-round-and-stretch.html
(3) border-image-slice-percentage-test.html
(4) border-image-space-001.html
