The touch area of the caret element includes the caret image and the
text above the image. This patch split these two areas, and call the
area covering the text "text overlay".

The children of the caret element already have unique class name like
"image" or "bar", we could change the class name to be id, and use id to
locate them.

On Fennec, it's possible that after automatically zooming an editable
input, the mImaginaryCaretRect for the caret remains the same. Only the
zoom level is changed. Therefore, the zoom level should also be
considered to determine whether the position is changed or not so that
the caret can get updated.

We want AccessibleCaret be of the same size regardless of the zoom
level. We simply divide the caret's width, height, margin-left, and the
text selection bar's margin-left by current zoom level.
The margin-left of the caret is adjusted from -23px to -23.5px for better
looking.
See AccessibleCaret.h for the class description.
Technical difference between AccessibleCaret and Touch/SelectionCarets:
The anonymous dom element containing a caret image will be created by
AccessibleCaret by using the API landed in bug 1020244 instead of being
created by nsCanvasFrame.
