Update the colours used when the system theme changes.
This is especially important to use the colour scheme compatible with
macOS 10.14+ dark mode.
Note that this commit is best viewed with "git diff --color-moved".

Add functions to enable or disable pages inside wxToolbook.
Using the new functions you can present disabled icons so that the user
can expect more functionality and you do not need to add/remove pages in
different states.

private field 'm_dwCookie' is not used
'return' will never be executed

potentially uninitialized local variable 'bound' used
The problem with MinGW 5.3 is not just due to the missing function
declaration in the header, but also due to the function missing from
libshell32.a import library, so we do need to load it during run-time,
contrary to what the comment in the previous commit said.
This should finally fix MinGW build.
At least the MinGW 5.3 used for AppVeyor builds doesn't declare this
function, so provide its declaration ourselves to fix MinGW build after
the recent changes.
Surprisingly, this doesn't seem to result in any ill effects, but
passing HICON to wxIcon already ensures that this HICON will be
destroyed in wxIcon dtor, so we shouldn't call ::DestroyIcon() on it
manually.
Avoid duplicating the same code in MSWGetBitmapForPath() and
CreateBitmap().
This also incidentally fixes SHDefExtractIcon() return value check,
which was inverted, in MSWGetBitmapForPath().
Use SHDefExtractIcon() to retrieve the most appropriately-sized icon
instead of always getting either the small or the large icon and then
scaling it ourselves to make it of the right size.
This results in incomparably better results for large icon sizes, e.g.
256*256, as can be seen in the artprov sample.
This way the first and only fallback language isn't necessarily the
msgid language (which is English most often). This is how GNU gettext
works -- it uses multiple fallback languages when multiple preferred
languages are set.
As a side effect, fixes#18227 in one possible way.
Use backticks around _UNICODE to avoid the special meaning of "_" in
Markdown.
Also use backticks around a couple of other identifiers/paths for
consistency.
lzma.h could not be found when building with wxUSE_LIBLZMA on macOS. Add
the found include directories and libraries from find_package(LibLZMA)
to the base library.
For consistency, add the include directories and libraries of all
find_package usage.
