• Status: RESOLVED FIXED

[Adam Barth]

layoutTestController.setBackingScaleFactor is redundant with (and less awesome than) internals.settings.setDeviceScaleFactor

I ran these tests on apple-mac on Lion in WebKit2 and they seem to still work (even when running --pixel-tests).

itnernals -> internals. perhaps "window.internals" to be clearer about what internals this means?

BackScaling -> BackingScale

how about:

setTimeout(layoutTestController.notifyDone);

?

why do we need a timeout at all?

> why do we need a timeout at all?

Dunno.  I'm just following the idiom used by the rest of the hidpi tests.  I assume it's because the callback from the injected bundle has a strange callstack and we want a clean call stack when we re-enter the LayoutTestController.

setTimeout(layoutTestController.notifyDone); would be simpler
