Remove WrapPreserve3DList() and replaced it by creating a
nsDisplayTransform item for each transformed frame.
- Add an additional item for each top frame extending 3D context to
separate consequence contexts.
- Effective transform of a layer is the accumulation of ancestors in
the same 3D context.
- The layers creating new context and extended by children need a
temporary buffer if it's effective transform is not 2D.
- Clip rects are accumulated along the context chain.
- Visible rects of items are computed from dirty regions of the frame
creating the context and accumulated transforms.
- Bounds of items are computed from accumulated transforms and
accumulated bounds of the descent frames.
- Backface hidden is handled by compositor and BasicLayerManager.

This make it easier to print a frame tag name in one debug log line.

The caret movement code already handles unselectable text frames if we
happen to land in the middle of one in nsTextFrame::PeekOffsetCharacter/Word.
However, when performing frame traversal to find the next frame to jump
to, we don't remember if we skipped over an unselectable frame, which causes
us to jump one offset too much when the caret is on the boundary of
selectable and unselectable content. The test cases demonstrate the
scenario. Note that an <img alt=foo> is implemented by adding a
generated content to the inline frame representing it, so as far as
the caret movement code is concerned, both test cases are treated similarly.
Note that we need to do this only when moving the selection, and not
when extending it. We are adding an aExtend argument to
nsPeekOffsetStruct's constructor in order to be able to special case
that.

The change to GetAfterFrameForContent prevents the reframe that is part
of the chain of events leading to this bug, and thus fixes the bug on
its own. The change to GetBeforeFrameForContent seems desirable for
symmetry.
Note that patch 6 also independently fixes the reported bug.
This probably needs somewhat careful review. We should examine:
(1) what the rules for calling nsLayoutUtils::GetBeforeFrame and
nsLayoutUtils::GetAfterFrame are, and whether both (or neither)
need to be patched.
(2) What the rules are for which frame the GenConProperty() lives on,
and whether we should adjust nsIFrame::GetGenConPseudos() to either
do something more intelligent, or assert about callers.
(We should probably clean up some of these things in a followup bug.)
Since the symptom of this bug is (once patch 4 is in the tree) only
causing extra reframes, it can only be tested using the new API (from
bug 1115691) for observing reframes. I confirmed that the test for this
bug fails without the patch and passes with the patch (as noted by the
removal of its todo annotation).
This patch fixes the assertion on layout/generic/crashtests/600100.xhtml,
though I haven't investigated why.
