c6a68f3de2 Fix dialog-less printing
We were sometimes ending printer enumeration prematurely,
and the code was confused about the meaning of found_printer.

The new setup follows these rules:
- We *only* end the search prematurely if found_printer
  is set, which indicates that we found the right printer
- We *always* call find_printer_idle exactly once, and
  make it return less than perfect matches like the
  default printer, or the first printer we found

d1aec0c3f1 actionmuxer: avoid duplicate and recursive work
If we've already done the tracking into the parent muxer, there is no need
to do it again. This can save a great deal of recursive work when adding
items to the muxer.

This makes showing the context menu in gnome-text-editor repeatedly fast
even as spelling corrections are changed.

It is likely that this could fix #4422 as well.

00d5f72d6e menutracker: reduce allocations and signal emission
When handling action-added callbacks the code was previously using a
freeze_notify/thaw_notify in all cases. This turns out to allocate a
significant amount of memory when called a lot.

That said, it shouldn't be getting called this much but given the current
state of affairs elsewhere in GtkActionMuxer, this brought temporary
allocations down from 9MiB to 9KiB in gnome-text-editor after showing
the context menu a few times.

* You can also use Drag-And-Drop to copy the data from the source to the

* #Keywords: game, mouse

* This demo shows how to use a GskPath to create a maze and use
* gsk_path_measure_get_closest_point() to check the mouse stays
* on the path.
*
* It also shows off the performance of GskPath (or not) as this

/**
* GskPathBuilder:
*
* A `GskPathBuilder` is an auxiliary object that is used to
* create new `GskPath` objects.
*
* A path is constructed like this:
*
* ```
* GskPath *
* construct_path (void)
* {
* GskPathBuilder *builder;
*
* builder = gsk_path_builder_new ();
*
* // add contours to the path here
*
* return gsk_path_builder_free_to_path (builder);
* }
* ```
*
* Adding contours to the path can be done in two ways.
* The easiest option is to use the `gsk_path_builder_add_*` group
* of functions that add predefined contours to the current path,
* either common shapes like [method@Gsk.PathBuilder.add_circle]
* or by adding from other paths like [method@Gsk.PathBuilder.add_path].
*
* The other option is to define each line and curve manually with
* the `gsk_path_builder_*_to` group of functions. You start with
* a call to [method@Gsk.PathBuilder.move_to] to set the starting point
* and then use multiple calls to any of the drawing functions to
* move the pen along the plane. Once you are done, you can call
* [method@Gsk.PathBuilder.close] to close the path by connecting it
* back with a line to the starting point.
* This is similar for how paths are drawn in Cairo.

"Approximation of circular arcs by cubic polynomials", Michael
Goldapp, Computer Aided Geometric Design 8 (1991) 227-238, provides
various values of h along with error analysis for each.
From that paper, a very practical value of h is:
h = 4/3 * R * tan(angle/4)
This value does not give the spline with minimal error, but it does
provide a very good approximation, (6th-order convergence), and the
error expression is quite simple, (see the comment for
