Reviewed by Eric Seidel.

FrameSelection stores its caret and repaint bounds in absolute coordinates. Absolute coordinates
we treat as pixel values, so this patch changes these values to integers. Sub-pixel precision
will still be used when these coordinates are passed down and used locally.

No new tests. No change in behavior.

* editing/FrameSelection.cpp:
(WebCore::absoluteCaretY): Uses absolute coordinates, which are ints.
(WebCore::FrameSelection::modify): Uses absolute coordinates to handle vertical selection
modification. Sub-pixel precision will be used when these values are converted to local ones.
(WebCore::CaretBase::absoluteBoundsForLocalRect): Absolute coordinates -> ints.
(WebCore::FrameSelection::absoluteCaretBounds): Ditto.
(WebCore::CaretBase::caretRepaintRect): The caret repaint rect is stored in absolute coordinates.
Reverting the values to ints.
(WebCore::FrameSelection::recomputeCaretRect): Ditto.
* editing/FrameSelection.h:
(FrameSelection):
* editing/mac/FrameSelectionMac.mm:
(WebCore::FrameSelection::notifyAccessibilityForSelectionChange): Switching to store absolute
coordinates as integers.
