[Wenson Hsieh]

When zooming (cmd +/-) or pinching to zoom with the trackpad, checkboxes and radio buttons should scale up in size instead of remaining at a fixed size.

This shouldn't be necessary. What is going on here?

[Wenson Hsieh]

Holding off on this until we understand why latter elements of the same size paint to existing IOSurfaces and make us render things incorrectly.

"Shouldn't be necessary" -> "is a leak".

This will be unblocked when http://trac.webkit.org/changeset/181301 is rolled out.

We should ask Tim here, but I wonder if we want ColorSpaceSRGB.

Couldn't get to Tim, but I asked Simon and he recommended ColorSpaceSRGB over device.
