This new invoker is able to handle all the palettes on a treeview,
removing the need of one invoker per cell renderer (CellRendererInvoker).
This simplifies the code and makes it more efficient.
Also removes the logic from the CellRendererIcon, which
should only care about drawing itself. [1]
Is important to note than in Gtk3 a CellRenderer is not a GtkWidget
then can't know when the mouse is over it or have the usual events
used by other invokers, making the implementation CellRendererInvoker
very complicate.
This commit also removes the invoker of CellRendererIcon.
The ScrollingDetector logic is simplified too,
because now there are only one invoker instead of one by renderer
and the example code updated.

Detecting if the treeview is scrolling we can improve the performance of
the CellRendererIcon by avoiding unneeded calculations.
The example scrollingdetector.py shows how this can be used. The
changes are backward compatible.

We are running the existing test_mime.py. All the other tests which
are not unit tests but more examples of code one can run interactively
are moved to the example directory.
This is only on a best-effort basis; the code will be in a broken state after
this patch and need to be fixed manually.
The purpose of committing the intermediate, non-working output is to make it
reproducible. It's impractical to manually review the changes.
The exact version used was 4f637212f13b197a95c824967a58496b9e3b877c from the
main pygobject repository [1] plus a custom patch [2] that hasn't been sent
upstream yet.
