This is mostly important to allow using wxImage-based wxGraphicsContext
without requiring X server connection under Unix: as wxFont can't be used
without X server, we needed another way to create wxGraphicsFont in this case.

Provide a way to use wxGraphicsContext to draw on wxImage.
This is implemented internally by drawing on wxGraphicsBitmap which can be now
also created from wxImage.
Add a test of the new functionality to the image sample.

Document wxGraphics{Context,Renderer}::CreateBitmap() and CreateSubBitmap()
and wxGraphicsContext::DrawBitmap() as well as the (trivial) class itself.

wxCompositionMode enum had a trailing comma not allowed by C++ 98 (and which
would result in warnings or errors with g++ pedantic switch).

Having an invalid element in wxCompositionMode enum allows to directly return
it from TranslateRasterOp() function instead of needing a separate bool
parameter to indicate that a ROP couldn't be translated.
This also incidentally fixes warnings about possibly uninitialized variables
in optimized g++ builds.

Use "wxWindows licence" and not "wxWidgets licence" (the latter doesn't
exist) and consistently spell "licence" using British spelling.
See #12165.

It may be convenient to create wxGraphicsGradientStop first and initialize it
later so allow doing this by providing the default argument for constructor
parameters and thus allowing to use it as the default constructor.
See #11897.

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.
Closes#11897.

The angles passed to it are measured clockwise from the horizontal axis,
contrary to the usual mathematical convention so take care to mention this in
the documentation.
Closes#11112.
