Fix loading user-defined icons for Qt plot window

Update both zoom/pan states on wx when triggering from keyboard.

Previously, typing "o" and "p" on a wx window would result in both the
zoom and the pan button being pressed at the same time.  Fix that by
relying on the same strategy as all other backends.

Switch transOffset to offset_transform.

Note that most APIs *previously* already accepted *offset_transform* as
kwarg, due to the presence of the `set_offset_transform` setter.  Prefer
that name (shortening it to `offset_trf` for local variables).

Backcompat for the old `transOffset` name is kept in most places by
introducing a property alias.

Passed on sides and pad_to

Use standard toolbar in wx.

The previous approach manually positioned the toolbar to have it at the
bottom of the window, but this can in fact be achieved just with
style=wx.TB_BOTTOM.

Removing manual sizing of the toolbar also fixes a bug previously
present on Windows, whereby a `set_size_inches` reducing the size of the
canvas would *not* reduce the window width, likely because it was forced
to its max value by the toolbar's explicit size.

Personally I use https:// as RO and ssh:// as RW, but I understand it
might not be convenient on windows.

Stop sorting artists in Figure Options dialog

With matplotlib#18216, the order that artists are added to an Axes is their
canonical order. The dialog should not be sorting them in some other
manner.

Additionally, this fixes a bug in that `apply_callback` indexes back to
the original list, which means that changes will be made to the *wrong*
artist if sorting actually occurred. It also makes the legend almost
entirely wrong as well.

See https://discourse.matplotlib.org/t/bug-on-re-generate-automatic-legend-of-matplotlib-figure-property/22511

Document ArtistList

DOC: Document default join style

in the same way as the default cap styles.

Jointly track x and y in PolygonSelector.

It's easier to track them in a single list.

Also init _selection_artist and _polygon_handles with empty arrays, as
there's no reason to pretend that they start with 0, 0.  On the other
hand, _xys does need to start as a non-empty array as the last point
gets updated as being the cursor position.

Fix typo in `tutorials/intermediate/arranging_axes.py`

Trivial doc fix to annotations tutorial.

Initially I just wanted to capitalize "matplotlib", but the wording was
a bit awkward too, so...

ENH: implement and use base layout_engine for more flexible layout.

FIX: typo

Remove some unnecessary getattrs.

Figures always have a canvas attached (even if it's just a
FigureCanvasBase), and canvases always have a "manager" attribute (which
may be None).

Canvases also always have a "toolbar" attribute (which also may be
None).

Altogether this allows avoiding a couple of getattrs.

FIX: Return value instead of enum in get_capstyle/_joinstyle

for MarkerStyle and Patch (as do Line2D, Collections and GraphicsContextBase)

(1) turn off the grid after creating colorbar axes (2) added a test

Cleanup "anatomy of a figure"

No visual change.

Improve formatting of "Anatomy of a figure"

- Adapt margins
- Reduce figure border width (still thick but not massive)
- fontfamily: make code monospace
- slightly move annotations to better places

Run wheel builds on PRs when requested by a label

Fix typos

Deprecate cleared kwarg to get_renderer.

This makes it easier for to mock the agg backend (e.g., in mplcairo).
Note that this is anyways only a shorthand for calling a method
(`.clear()`) on the renderer itself, so just issuing that call is just
as simple, more explicit, and can be done even when one just has access
to the renderer and not to the canvas (an admittedly rather hypothetical
case).

Improve ft2font error reporting.

This prints out human-readable error messages for failures.

As an example, `FT2Font("setup.py")` now raises
```
RuntimeError: In FT2Font: Can not load face (unknown file format; error code 0x2)
```

Ensure that all toolbar (old/new) subclasses can be init'ed consistently

i.e. with the same signature: with `canvas` as sole arg for the
old-style toolbars, with `toolmanager` as sole arg for the new ones.

Subclasses that explicitly support setting a parent widget keep that
support (except for gtk, which stashed that in the `.win` attribute but
never used it), but that argument is always optional now; the default is
the canvas' parent.

The goal is to later replace all _get_toolbar implementations by a
simple call (always with the same signature (dependent on the value of
rcParams["toolbar"])) to the correct class in the FigureManagerBase
constructor.

Fix Qt enum access.

This was missed in the global fixing of enums for PyQt6 (now using
_enum everywhere).  To trigger, try to interactively save a figure but
input an invalid format, e.g. "foo.bar".

MNT: deprecate filled parameter to colorbar

The *filled* kwarg doesn't directly do anything and filling is
completely controlled by the mappable.

OTOH, maybe we want to reinstate the ability of *filled* to fill
contours?

Deprecate colorbar.draw_all.

Merge main and "other" params docs in colorbar.make_axes.

`colorbar.make_axes` (and `make_axes_gridspec`) are low-level enough
that it's not worth the complexity in docstring interpolation to split
out "main" parameters and "other" parameters, when the docstring of
the more commonly used `plt.colorbar` smashes them together.  (Also,
`pad` is not really much more low-level than `shrink` or `aspect`...)

Numpydocify _colormap_kw_doc and use it in Colorbar too.

Display bad format string in error message.

I had something like `for i in range(n): plot(..., f"oC{i}")` which
works for n up to 10, but for greater values one gets "oC10" which is
not supported (which is reasonable, as some single-digit strings are
actually *marker* abbreviations); mentioning the full format string in
the error message ("Unrecognized character 0 in format string 'oC10'")
makes it clearer.

FIX: bury import of matplotlib.font_manager

We need to ensure that the sub-module matplotlib.font_manager is imported when
it is used in SclarFormater, however if we import it at the top level we will
get circular imports.

closes matplotlib#22305

In mpl_toolkits, use the same floating point slop as for standard ticks.

Standard ticks use _interval_contains_close (in Axis._update_ticks); do
the same in mpl_toolkits and deprecate the custom slops delta1, delta2
(if such knobs are really needed, we should try to have the same API in
the main library anyways).

FIX: use window_extent instead

Add set_cursor method to FigureCanvasTk

Don't warn on grid removal deprecation is grid is hidden

Fixes matplotlib#21723.

See matplotlib#21723 (comment)
for a full desciption of motivation and edge cases.

Modify example for x-axis tick labels at the top

Primarily describe how to do this for a single Axes (using `tick_params`).
Only mention the `rcParams` in a note. Globally changing `rcParams` is
usually not a good idea and should not be demonstrated. The whole
topic of `rcParams` (global, context, matplotlibrc) is too long to
be discussed here and not the focus of the example.

Remove Axes sublist modification from docs

Rework/fix Text layout cache.

Instead of caching the text layout based on a bunch of properties, only
cache the computation of the text's metrics, which 1) should be the most
expensive part (everything else in _get_layout is relatively simple
iteration and arithmetic) and 2) depends on fewer implicit parameters.

In fact, the old cache key was insufficient in that it would conflate
usetex and non-usetex strings together, even though they have different
metrics; e.g. with the (extremely artificial) example
```python
figtext(.1, .5, "foo\nbar", size=32)  # (0)
figtext(.1, .5, "foo\nbar", usetex=True, size=32, c="r", alpha=.5)  # (1)
figtext(.3, .5, "foo\nbar", usetex=True, size=32, c="r", alpha=.5)  # (2)
```
the linespacing of the first usetex string (1) would be "wrong": it is
bigger that the one of the second usetex string (2), because it instead
reuses the layout computed for the non-usetex string (0).

The motivation is also to in the future let the renderer have better
control on cache invalidation (with a yet-to-be-added renderer method),
e.g. multiple instances of the same renderer cache could share the same
layout info.
