The introduction of scrollbar animations broke scroll-to-end functionality when
large amounts of text are written, due to interactions with GtkTextView's
background layout. Work around this by scrolling after the layout has finished.

Fix a bug with wrong size passed to memset() introduced in 1f0ade29f0
(Fix using mask colour even if there is no mask in wxImage::Paste,
2020-09-30) which caused memory corruption and add a test (the one with
the large negative vertical offset) allowing to reproduce this reliably.
Closes https://github.com/wxWidgets/wxWidgets/pull/2067
Also update the test to avoid assuming that wxBitmapComboBox inherits
from wxComboBox, which now allows it to build (and pass) on all
platforms.
Closes https://github.com/wxWidgets/wxWidgets/pull/2057
In case an image without alpha is pasted on top of an image with alpha,
the alpha blending gives wrong results. This is caused by the fact that
the final (if nothing has been pasted yet) pixel copying algorithm in
Paste() does not take into account whether the pasted image actually
uses a mask.
To fix this:
- Add the check for image.HasMask().
- In case there is no mask, simply copy the image via memcpy.
- Finally, update the alpha channel of the changed image (if present):
whenever a pixel is copied, the alpha is set to fully opaque.

Generic wxDC::DeviceToLogicalRel{X|Y}() and wxDC::LogicalToDeviceRel{X|Y}()
functions don't take into account scaling applied with
wxDC::SetTransformMatrix().
We need to implement in wxDCImpl and its platform-specific derivates
new conversion functions that take all applied transformations into account.
See #18923.
Now that this class is not a template any longer, we can have the code
for radio button group navigation directly in it, without making it
inline, so move the existing functions bodies into the new methods and
remove the old functions entirely.
No real changes, this is just a refactoring.
This requires adding a couple of const_cast<>s in their implementation
in order to still allow them returning non-const wxRadioButton pointers,
but this seems preferable to not being able to call them on a const
wxRadioButton in the first place.
Previously they were only used, and compiled, on the platforms without
wxHAS_NATIVE_TAB_TRAVERSAL, i.e. were not compiled at all in wxGTK, but
we now need them everywhere as they're used to implement public API.
wxCmpNatural() had "inline" function specifier in a .cpp file
which made the function inaccessible outside that file in static builds.
Fix this by removing "inline", the function character is such that the
overhead by a function call should have negligible impact on its
performance.
Closes https://github.com/wxWidgets/wxWidgets/pull/2050Closes#18919.
This is a micro-optimization after the previous commit: don't call
FindToolByPositionWithPacking() at all rather than calling it and then
ignoring its result if wxAUI_TB_NO_TOOLTIPS style is set.
This commit is best viewed ignoring whitespace.
And use it to get HiDPI support wherever we use GtkImage. This extends and
consolidates support for custom drawing of images which has already been added
somewhat redundantly in several places.
Generic wxDC::DeviceToLogical{X|Y}() and wxDC::LogicalToDevice{X|Y}()
functions don't take into account transformations applied with
wxDC::SetTransformMatrix() so conversion results are invalid if wxDC is
transformed with both e.g. wxDC::SetUserScale() and
wxDC::SetTransformMatrix().
We need to implement functions in wxDCImpl and its platform-specific
derivates to do this conversion with taking into account all applied
transformations.

* static string via accessor
* striping off xml preamble unconditionally
if we use a different format in the future, we will have to increase our version number
* applying italic directly to the font descriptor
thus preserving attributes in the native font descriptor which we don’t store explicitly yet
* Adding support for preserving font width
Although we don’t express this in the public API yet, we try to preserve eg condensed, when changing the font width
* Adding reference, bug fix
double checked the font weight constants,

This fixes another problem similar to the one fixed in be1854c617 (Avoid
UI functions in non-main thread in wxGStreamerMediaBackend, 2020-09-02)
and does it in a similar way: SetupXOverlay(), which calls gdk_flush(),
was called from gst_bus_sync_callback() which is executed in the worker
thread, so use CallAfter() to call it from the main thread later.
In aa2cd42206 (Report video size changes to the media backend,
2016-02-22), a couple of calls to NotifyMovieSizeChanged() were added,
presumably for a good reason. Unfortunately, NotifySizeChanged() makes
UI calls on wxGTK, so this resulted in UI calls happening on a non-main
thread because many of GStreamer's callbacks occur on arbitrary threads.
This is bad because it caused random X11 crashes.
Fix this by calling NotifyMovieSizeChanged() with CallAfter().

Draw wxTextCtrl focus ring natively on Mac.
Add wxWindow::EnableVisibleFocus() to explicitly control the focus ring
visibility if necessary.

Although @"UIApplication" is supposed to be used by default anyhow,
passing "nil" is reported to result in an assertion failure in
'_UIApplicationGetPrincipalClass' when running under the iOS 13.1
simulator, so pass this string explicitly.
