Subpixel rendering: Setting content to opaque on m_graphicsLayer depends on subpixel accumulation.
https://bugs.webkit.org/show_bug.cgi?id=129776
Reviewed by Simon Fraser.
isEmpty() returns true when any of the dimensions is <= 0. Subpixel accumulation could happen
in one direction only. Use isZero() instead().
