356e0725d8 Move wxGraphicsRenderer::CreateContextFromUnknownDC() around
No real changes, just move this method to the implementation section of
its class.

8bbac921f3 Add wxGraphicsRenderer::CreateContextFromUnknownDC()
It seems wrong to have this function in wxGraphicsContext only and not
in wxGraphicsRenderer, as this makes it impossible to create a context
associated with a non-default renderer while it doesn't cost us anything
to allow doing this.

46188ff56f Remove dynamic_cast-based implementation of CreateFromUnknownDC()
There doesn't seem to be any point to have both wxRTTI-based
implementation and the standard RTTI-based one, so leave the former one
only.

8fbca5cb70 Remove all trailing spaces
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.

This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.

5e53b22bd4 Add wxGraphicsContext::GetWindow()
This method allows to retrieve the window this context is associated
with, if any.

Add "wxWindow*" argument to wxGraphicsContext ctor and provide the
window pointer to it when available, i.e. when creating the context from
a wxWindow directly or from wxWindowDC, which is also associated with a
window, in platform-specific code.

No real changes yet.

713a7ab895 Move wxUSE_ENH_METAFILE check inside wx/msw/enhmeta.h itself
This is more consistent with the other headers, which are safe to
include even when the corresponding feature is turned off.

Also remove the now redundant wxUSE_ENH_METAFILE checks in the source
code including this header.

9acb2fe3a0 Fix AddArcToPoint when no current point is set on wxGraphicsPath
Current behavior of AddArcToPoint() when there is no current point is not
documented and moreover it is not the same in native macOS and in generic
implementation. Under macOS nothing is done and "no current point" error
is raised but under other ports (generic implementation) only arc
is drawn (without initial line).
When there is no current point, in similar functions AddCurveToPoint(),
AddQuadCurveToPoint() it is initially set to the some known control point
of the curve but this approach cannot be applied to AddArcToPoint().
The only well defined fallback point seems to be (0, 0) and this option
is implemented here.

See #18086.

60669e9b50 Harmonize wxGraphicsPathData::AddArcToPoint() behaviour across all ports
AddArcToPoint() on macOS port is implemented with native API (CGPathAddArcToPoint) so its behaviour should be considered as a reference for generic implementation used in another ports.

4d388e351c Fix Direct2D graphics context after wxPenInfo changes
At least in wxMSW wxPen::GetStipple() returns a non-null (but invalid)
bitmap even when pen style is not wxPENSTYLE_STIPPLE, so don't test for
this bitmap when creating a wxGraphicsPen from a wxPen but for the style
directly.

This avoids using this invalid bitmap later in D2D code, where it
resulted in assert failures.

Also add a similar style test before calling wxPen::GetDashes() for
consistency, even if it doesn't seem to be strictly necessary.

See https://github.com/wxWidgets/wxWidgets/pull/553

Closes #17958.

8bad0e494f Get rid of wxGraphicsPenInfo::CreateFromPen()
This is a helper method used only in wxWidgets itself and only once, so
just inline it at the point of use to avoid exporting an unnecessary
function in the public API.

76fd05b147 Leave only wxGraphicsRenderer::CreatePen(wxGraphicsPenInfo) overload
It doesn't make much sense to require all the graphics backends to
create wxGraphicsPen from either wxPen or wxGraphicsPenInfo when the
former can be handled just once in the common code.

So do just this, leaving CreatePen() overload taking wxGraphicsPenInfo
where the real pen construction takes place and implementing
wxGraphicsPen creation from wxPen in the common wxGraphicsContext code.

This is not 100% backwards-compatible as any code inheriting from
wxGraphicsRenderer and overriding its CreatePen() will now be broken,
however this should be extremely rare (there is no good reason to
inherit from this class in the user code) and result in compile errors
if it does happen.

81d9208424 Optimize adding rounded rectangle to wxGraphicsPath
In AddRoundedRectangle() we know in advance (angle = 90 deg) or can easily determine (center point) parameters of all arcs at the vertices of the rectangle so instead of using AddArcToPoint() function which is generic and hence computationally expensive we can use AddArc() function which implementation is simpler and execution should be faster.

3f66f6a5b3 Remove all lines containing cvs/svn "$Id$" keyword.
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.

Closes #14487.

fa378d369f Allow creating wxGraphicsFont without using wxFont.
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.

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.

b129eaa377 Implement wxGraphicsContext::GetSize() for Cairo.
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.

of a pair of colours.

for now.
