Garbage when rubber-banding at the right edge of a page zoomed to non-integral scale.

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[zalan]

1. Navigate to about:blank.
2. Zoom in (but not all the way! you need to be at a non-integral scale).
3. Rubber-band off the right edge of the page.

I think you should just return m_usingTiledCacheLayer.

It looks like this caused platform/mac-wk2/tiled-drawing/tile-size-slow-zoomed.html to start failing on the bots.

Here's the results on the Mavericks bot: http://build.webkit.org/results/Apple%20Mavericks%20Release%20WK2%20(Tests)/r169162%20(5869)/results.html

Here's the history of the bot which shows that it started failing reliably after this revision: http://build.webkit.org/builders/Apple%20Mavericks%20Release%20WK2%20%28Tests%29?numbuilds=100

Nevermind, the results were re-baselined in a later fix.
