This adds an additional screen to the drawing sample showing all available wxSystemColour values. It makes sense for testing these values but also provides a convenient overview of available colours for the library user.
For some systems (like OS X, GTK+ 3) drawing with transparency is supporting by native wxDC and in this case "Alpha screen" sample can be shown even if wxGraphicsContext is not used/enabled. For such wxDC's all drawing operations can be done directly without using wxGraphicsContext.
Because graphics renderer is not only selected via menu but also directly in the application (in MyFrame::OnShow) there is necessary to update menu items responsible for selecting graphics context to represent current state of the application.
This is done in EVT_UPDATE_UI handlers where there is checked what graphics renderer is currently in use and state of the menu items is updated accordingly.
Closes#16971.
It was confusing to not see anything when selecting one of the screens using
wxGraphicsRenderer if a renderer hadn't been selected from the menu before.
Switch to using wxGC automatically now if one of these screens selected and
there was no previously selected renderer.
In particular, allow switching between GDI+ and Direct2D under Windows, which
is very convenient for comparing the rendering results.
This can also be useful when using Cairo.

No real changes, just make the "File" menu (which was also renamed to
"Drawing" as it has nothing to do with files) less long by splitting off the
screen selection in a separate menu.

This is not only wasteful, but creating a Direct2D surface associated with a
wxDC makes it impossible to paint on the DC using GDI functions, so this
completely broke the initial display in the sample.

This shows inconsistency in handling of radial gradients with and without
stops in current wxMSW GDI+-based wxGraphicsContext implementation.

Replace them with wxFONTWEIGHT_BOLD, wxFONTSTYLE_NORMAL or wxFONTWEIGHT_NORMAL
and equivalents in the code of the library itself and in the samples.
Also simplify font construction using wxFontInfo where possible to avoid
specifying these constants at all if they are not needed.

This change slightly improves wxBufferedDC and wxBufferedPaintDC behaviour
when the origin of the DC is shifted, but they still don't work quite right in
this case as they don't use the buffer area of correct size in this case,
which results in cropping the final bitmap (as can be seen in the drawing
sample, which was modified to show wxBufferedPaintDC in action).
Closes#15497.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.

Add a special symbol which is defined only if the icons and other images (e.g.
cursor) are in the separate resource files and don't need to be embedded as
XPMs in the main program.
This makes the checks more clear and more customizable as it's enough to
change wxHAS_IMAGES_IN_RESOURCES definition instead of changing many platform
checks.

MS and Apple guidelines mention ellipses should generally be used when a command needs additional information from the user before the operation can execute. This is not the case for showing an about dialog so the ellipses have been removed.

VC6 can't instantiate member template functions so get rid of it and use ugly
dynamic casts in the non-template function to construct wxGCDC correctly.

This allows to test wxMemoryDC and, under MSW, wxMetafileDC and also can be
used to compare the output of different versions of the sample (possibly from
different ports, too).

Additionally renamed wxOSX' private wxNativePrinterDC::Ok() function to IsOk().
Didn't deprecate the various Ok() functions: given the amount of changes already introduced in 3.0 a trivial one like this seems more suitable for after 3.0.

The rubber banding selection message box was shown even after a simple click,
i.e. when nothing was actually selected which was quite annoying, so don't do
this.
Also remove unnecessary casts and use wxLogMessage() instead of
wxString::Printf() + wxMessageBox().

It is definitely not necessary to call SetTopWindow() when there is only a
single top level window and it is arguable whether it's useful to do it even
when there are many of them so don't encourage its use in the documentation
and also remove all its occurrences from the samples.

Native wxMSW wxDC::DrawText() implementation doesn't support multi-line
strings so use the generic wxDC::DrawLabel() code instead. Drawing multi-line
strings now works at least in wxGTK and wxMSW, to be tested for the other
platforms.

Standardize on using sample.rc and sample icon in all the samples, it was
confusing that some of them used it and other didn't, without any apparent
logic.
Remove the now unnecessary icon files, including the dialogs sample icon which
seemed to be corrupted (this closes#11146).
Also replace multiple OS/2 resource files with a single one in the sample
directory. The OS/2 projects/makefiles would need to be updated to use them.
Remove dialogs sample icon.

We must offset the coordinate system before scaling it, otherwise incorrect

Hardcoding position to 50,50 is inconvenient, let the window manager position
the window as configured by user. Also, the vertical size of the sample was
too small to see the contents of most pages, increase it.

Allow specifying a set of gradient stops instead of just the beginning and
ending colours. Add the new wxGraphicsGradientStop(s) classes and new
wxGraphicsContext::Create{Linear,Radial}GradientBrush() overloads. Also change
the same methods of wxGraphicsRenderer to take wxGraphicsGradientStops instead
of a pair of colours.
Implement the new API for MSW and Cairo. OS X still uses just the two colours
for now.
