Bug 121859 – [mac] Stop using DrawingAreaImpl on PLATFORM(MAC)

• Component: WebKit2
• Status: RESOLVED FIXED

[Tim Horton]

We should be using TiledCoreAnimationDrawingArea everywhere, including for tests. It should be the only drawing area you can acquire when making a WKView, and should happen automatically.

This would be relatively straightforward, except for two things:

* TCADA currently explicitly forces use of threaded scrolling, which breaks a number of tests. These two things aren't necessarily related and should be decoupled.

* Using tiled drawing means the layer tree dumps will be slightly different for some tests, so we need to adjust layer tree output to be consistent (otherwise Mac-WK2 will be different from Mac-WK1 and all the other ports).

Sounds like something that I didn't cause.

I filed a bunch of bugs about test regressions:

https://bugs.webkit.org/show_bug.cgi?id=122233 - A variety of regions tests have overflow which is not accounted for, and fail
https://bugs.webkit.org/show_bug.cgi?id=122234 - A bunch of tests fail with minor color mismatches (I'm going to look at this one next, along with some other things)
https://bugs.webkit.org/show_bug.cgi?id=122235 - Some css3/ tests fail with fringing around tiled background-images that intersect tile boundaries
https://bugs.webkit.org/show_bug.cgi?id=122237 - fast/table/crash-section-logical-height-changed-needsCellRecalc.html asserts
https://bugs.webkit.org/show_bug.cgi?id=122238 - fast/layers/no-clipping-overflow-hidden-added-after-transform.html fails with tiled drawing
