This patch adds a change hint to signal that one of the offsets on a
frame has been changed. When processing the hint, we do one of the
following things based on the position property of the frame.
* For static frames, we ignore the offset changes completely, as they
will not change the layout.
* For relative positioned frames, this patch refactors the
nsHTMLReflowState::ComputeRelativeOffsets function so that it can be
used from other callers, and it uses that to compute the new relative
offsets, and uses the offsets computed previously to compute the new
position of the frame.
* For absolute positioned frames, we set up a fake parent reflow state
object, and then we create a new reflow state object for the frame in
question. This setup is similar to what nsFrame::BoxReflow does.
Once we have the new reflow state object, we use it to compute the
absolute offsets, and then we use the computed offsets to set the new
position of the frame. The offset computation is similar to what
nsAbsoluteContainingBlock::ReflowAbsoluteFrame does. In some cases
where it is possible for the dimensions of the frame to change based
on the offset changes, we fall back to a full reflow.
This patch ensures that the NODE_IS_EDITABLE flag is only set on nodes living
under an editing host. Things like text controls which used to have that flag
previously will not have it any more. The flag would be set on their anonymous
div node instead. Note that if text controls actually fall under an editing
host, they will get the NODE_IS_EDITABLE flag.
This patch also makes nsHTMLEditor::IsEditable return sane results (text nodes
are always considered to be editable).

We make html canvas frame a container and render frames for its content which makes a lot of what we need for accessibility "just work".

The fix checked in for bug 720987 caused a major rendering regression with
native fennec. Revert it for transformed frames until the correct fix is found.
