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.

wxGDIPlusFontData only needs wxGDIPlusContext to get the font unit to use, so
pass the font unit directly to the ctor to allow also using it when there is
no context at hand.

Remove the now unnecessary default ctor from wxGDIPlusContext and
wxGDIPlusMeasuringContext and add a ctor taking just wxGraphicsRenderer that
can be useful to the derived classes instead.
Merge Init() and SetDefaults() and initialize everything at once in the new
Init() now.

This doesn't make any sense because classes such as wxGDIPlusContext,
wxGDIPlusMeasuringContext and wxMacCoreGraphicsContext are private and don't
need to be creatable by name (only renderers potentially need to be) and was
inconsistent with Unix/Cairo backend in which these classes were not dynamic.
So remove wxRTTI macros from them in wxMSW/wxOSX as well as this allows us to
get rid of unnecessary default ctors.

done for GDI+.
* Enable the use of the wxCairoContext on MSW.
* Enable creating a wxGCDC from an exisiting wxGraphicsContext.
* Since it's possible for a DLL that is using wx to not be on the PATH nor in
the same location as the .exe, change the wxDynamicLibrary::RawLoad method to
explicitly look first in the same place as the main wx-using binary. This way
it will find DLLs that are in the same folder as the wx-using binary even if
that would not be in the normal DLL search path.
* Change wxDCImpl and wxDC::GetLogicalScale to be const methods.

g++ (usefully) warns when assigning NULL to a non-pointer in wxGDIPlusRenderer.
Just use 0 instead of NULL to avoid the warning.

Using PopState() without a previous PushState() is an error but it shouldn't
result in a crash, so add an assert guarding against it.

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.

We didn't draw the last line and row of the image for some reason, simply
remove the -1 which prevented us from doing this.

As the implementation of this method is basically the same for all ports move
it to the base class itself instead of requiring the derived classes to
implement it. Now the derived classes need to fill in m_width and m_height
members instead.
Do fill them when creating wxGraphicsContext in Cairo version.

Include wx/stack.h, which includes the standard <stack> header, before
<windows.h> as the latter redefines min and max as macros conflicting with the
standard headers.

This is still simpler than std::stack<> which can be used with any container
and not just wxVector<> but better than the WX_DECLARE_STACK() macro which was
all that we had before.

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.

wxDC::GetTempHDC() method provides a convenient and safe way to retrieve HDC
from a wxDC object, whether it is using GDI or GDI+. It is implemented using
(MSW-specific) virtual functions in wxDC and so doesn't need ugly hacks like
wxDynamicCast which were used in src/msw/renderer.cpp to achieve the same
effect.
Also, we now use GetTempHDC() consistently in all wxMSW rendering methods as
the old GraphicsHDC was only used in some of them meaning that many methods
didn't work at all with wxGCDC.

This commit is huge but there are no non-white-space changes in it.
Some files containing third-party sources (src/msw/wince/time.cpp,
src/x11/pango*.cpp) were left unchanged.
