Fix aspect ratio for rounded background image size

Fix aspect ratio for rounded background image size

The previous calculation to maintain aspect size when one
background image dimension is round and the other is auto
was using the new tile size for the rounded dimension for the
aspect ratio calculation, which is wrong. This change switches
to using the original aspect ratio.

New tests for both horizontal and vertical cases.

Locally some tests have new results:
svg/as-background-image/background-repeat.html was wrong is now correct.
ietestcenter/css3/bordersbackgrounds/background-size-aspect-ratio.htm was wrong
is now correct.
fast/backgrounds/background-repeat-with-background-color.html now correct but a
badly designed test. Will change.
css3/masking/mask-repeat-round-auto1.html was wrong now right needs new ref
result
css3/masking/mask-repeat-round-auto2.html was wrong now right needs new ref
result
css3/background/background-repeat-round-auto1.html was wrong now right needs new
ref result
css3/background/background-repeat-round-auto2.html was wrong now right needs new
ref result
