In case we had a toplevel window W1, the paint was triggered for window
W2 and we had a sub-widget W3, then previously the buffer was created
for W2, so the pixel offsets had to be set relative to W2 when rendering
W3. As a consequence, if a single window was painted, then it was
always painted in the top left corner.

Now that the buffer is persistent and is always created for W1, make
sure that we paint to the correct offset, and W3 is always painted at
the same offset, regardless if it was painted directly, or just because
it's a child of W2.

With this, the buffer conents is closer to what is on the screen, even
if it's not perfect yet.

The listeners were stored in a std::list which is not efficient for
the lookup required in EndListeningHiddenRange()

The list was replaced by an std::unodered_map which allows faster
look-up.

No need to call it in PaintHelper::StartBufferedPaint(), which would
happen only for the root of the paint hierarchy. It's enough to do it in
PaintHelper::DoPaint(), which happens for each widget.
