[iOS] Frame snapshots don't factor in page scale
https://bugs.webkit.org/show_bug.cgi?id=147239
<rdar://problem/21905756>
Reviewed by Simon Fraser.
* page/FrameSnapshotting.cpp:
(WebCore::snapshotFrameRect):
Apply page scale when determining the backing store size and setting up the context.
* page/TextIndicator.cpp:
(WebCore::TextIndicator::createWithSelectionInFrame):
Don't assume snapshotFrameRect gave us an image with scale=deviceScale, because it
will factor in the pageScale too.
* platform/graphics/ImageBuffer.h:
(WebCore::ImageBuffer::resolutionScale):
Expose resolutionScale.
* rendering/RenderLayerCompositor.cpp:
(WebCore::RenderLayerCompositor::addToOverlapMap):
This has been true for a long time.
