Previously, it was using a paint invalidation method. That is less
efficient, and also wrong if the renderer is a squashed layer.

* Source/WebCore/rendering/RenderElement.h: Update "paint" function to to have "paintOffset" and also add comment for explanation
* Source/WebCore/rendering/RenderObject.h: Update Comment and remove "selectionRect" function
* Source/WebCore/rendering/RenderWidget.cpp: Fix paint logic for selected widgets and remove "FIXME" about selectionRect
* LayoutTests/editing/selection/iframe-select.html: Added Test Case
* LayoutTests/editing/selection/iframe-select-expected.html: Added Test Case Expectations
