Make Get[MultiLine]TextExtent() behave consistently for empty strings on
all platforms, in particular return (0, 0) size for them from
GetTextExtent() in wxGTK, which is an incompatible change but is needed
to make it behave in the same way as the others.
See https://github.com/wxWidgets/wxWidgets/pull/1970
This seems more logical and is compatible with wxDC in wxMSW and wxGTK2,
as well as other kinds of DC, e.g. wxPostScriptDC.
It also looks like the current behaviour was unintentional as it
happened only because wxGCDCImpl::DoGetTextExtent() always passed all
non-null parameters to wxGraphicsContext::GetTextExtent(), even if it
didn't need the values for all of them, and thus bypassed the special
case for the empty string which was already present in the latter
function.
Fix this, making DoGetTextExtent() more efficient as a side effect (we
now avoid unnecessary calls to pango_layout_iter_get_baseline() in the
most common case), and also add another test for empty string to
wxGraphicsContext itself, for non-GTK case.
Also document this behaviour and add a test checking for it.
The fix for OpenGL coordinates when using high DPI in b134589cbb (Fix
OpenGL samples when using HiDPI displays, 2019-08-06) did fix it for GTK
3 and macOS, but broke it for MSW and other platforms not using pixel
scaling, as window coordinates are the same as OpenGL ones there, while
GetContentScaleFactor() can still return values > 1 even on these
platforms.
Provide new GetOpenGLScaleFactor() function abstracting this platform
difference and use it in all OpenGL samples to make them work correctly
in high DPI under all platforms.

Since OS X 10.12 it has been named macOS so it makes sense
to reference it in documentation as such, even when it
sometimes refers to older versions which were called (Mac) OS X.
Now that desktop Macs using ARM exist, we should default to building the
normal, macOS-targeting, port on them and not wxiOS any more.
This is a backwards incompatible change, but it shouldn't affect many
people, so should hopefully be fine.
GetPaths/GetFilenames() must be used instead when more than one file
could be selected: document this and assert if the wrong functions are
called.
Closes https://github.com/wxWidgets/wxWidgets/pull/1883
Mention that RecalcSizes() shouldn't be called any more, after the
changes of 622deec262 (Replace wxSizer::RecalcSizes() with
RepositionChildren(), 2015-10-11), and that RepositionChildren()
replacing it shouldn't be directly called neither.
Document bakefile version needed and the commands for regenerating the
files generated by it.
Also update instructions for changing C:R:A values.
Closes https://github.com/wxWidgets/wxWidgets/pull/1838
This is now done automatically in the GitHub action of wxWidgets/website
repository.
Do mention that rebuilding the web site requires the release to be
available.
This is more user-friendly than GitHub links with their tons of files.
Also use the recently added #vX.Y.Z_msw anchor to link directly to MSW
binaries downloads from the corresponding file.
Closes https://github.com/wxWidgets/wxWidgets/pull/1820
Make command line instructions for vcpgk more similar to those used
for example for nmake. The MS Windows command line does not use $ as
the command prompt and batch files are more commonly used then Unix
shell scripts.
Closes https://github.com/wxWidgets/wxWidgets/pull/1785
This allows to easily test for the native control existence and also
whether wxGenericAnimationCtrl is really different from wxAnimationCtrl.
It also allows to avoid explicit check for wxGTK in common code.
This file doesn't need to be created initially, as it will be done
automatically during the build, but it does need to be updated whenever
setup0.h changes, so explain this in both the README-GIT.md file and the
main build instructions.
Closes#18699.
This doesn't work anyhow, so it's better to prevent the code doing this
from compiling instead of getting run-time asserts or worse.
Also simplify construction of these events inside wxWidgets by passing
the window itself to the ctor instead of passing just its ID and calling
SetEventObject() separately later.
For consistency, do the same thing for wxNcPaintEvent too.
