<rdar://problem/9028929> REGRESSION (r75897): Scaling applied twice to an iframe with a transformed ancestor

Reviewed by Maciej Stachowiak.

Source/WebCore: 

Test: fast/frames/iframe-scale-applied-twice.html

* page/FrameView.cpp:
(WebCore::FrameView::create): Set the initial bounds of the view to match the
frame size.
* platform/ScrollView.cpp:
(WebCore::ScrollView::visibleContentRect): Based on bounds, not frame size.
(WebCore::ScrollView::updateScrollbars): Ditto.
(WebCore::ScrollView::setFrameRect): Moved code that really handles bounds size
change to setBoundsSize().
(WebCore::ScrollView::setBoundsSize): Added.
(WebCore::ScrollView::setInitialBoundsSize): Added. Sets the bounds size but does
not update anything.
(WebCore::ScrollView::frameRectsChanged): Based on bounds, not frame size.
(WebCore::ScrollView::scrollbarCornerPresent): Ditto.
* platform/ScrollView.h:
(WebCore::ScrollView::boundsSize): Added this getter.
* platform/Widget.h:
(WebCore::Widget::resize): Set the bounds size to the frame size.
* platform/mac/ScrollbarThemeMac.mm:
(WebCore::ScrollbarThemeMac::paint): Fixed an error in the indirect drawing code
path where the buffer rect was resized to capture only the damaged part, but was
still drawn in the original location.

LayoutTests: 

* fast/frames/iframe-scale-applied-twice-expected.txt: Added.
* fast/frames/iframe-scale-applied-twice.html: Added.
