fixed a press/release pan bug when mouse button=2 as described in sf bug 2805312

Try to improve the cursor readout and status message.
This could be done better with changes to the backends.
The status (pan/zoom etc) should be indicated via the
state of the buttons, e.g. using radio buttons, rather
than by printing text. The readout should be positioned
to minimize jumping around of the text.

applied Michiel's sf patch 2792742 to speed up Cairo and macosx collections

print_ps with mixed-renderer

use 0 for default in rec join outer join if no default given

Fixed a bug in mixed mode renderer that images produced by
an rasterizing backend are placed with incorrect size.

Change default joinstyle to round

Rework the nan-handling/clipping/quantizing/simplification
framework so each is an independent part of a pipeline.
Expose the C++-implementation of all of this so it can be
used from all Python backends. Add rcParam
"path.simplify_threshold" to control the threshold of
similarity below which vertices will be removed.

Improved tight bbox option of the savefig

bbox_inches option for savefig
