If nothing else, this avoids 2 calls to each of wxGetDisplaySize() and
wxGetDisplaySizeMM() on each and every wxGCDC construction which are
completely unnecessary as wxGCDCImpl uses its own hardcoded resolution
of 72 DPI, as do some other classes deriving from wxDCImpl.
And even for the classes which do compute these fields using the display
resolution, it may still be unnecessary to do it as they can be never
used if neither GetSizeMM() nor SetLogicalScale() are called on the
corresponding wxDC object.
Finally, this is more than an optimization as when using Cairo-based
wxGCDC without display (which is explicitly supported), calling
wxGetDisplaySize() simply doesn't work at all.
This function always returns true in practice and it's completely
useless to call it during each wxDC object construction, especially
because wxDC::m_colour itself is not used anywhere.
The new method returns a boolean flag which indicates whether there is
any clipping region or not and so is preferable to using the old one and
checking its return value to determine this, which can't be done
reliably.
There is no need to call neither ResetBoundingBox() nor ResetClipping()
when the variables they reset had just been initialized to the same
values in the ctor initializer list.
Determining whether there is an actual clipping region or not is not
that simple, as shown by the recent problems in wxDCClipper code, so
return a boolean value indicating this from GetClippingBox() directly,
instead of requiring the caller to find it out on their own.
This simplifies wxDCClipper code, as well as any other code calling
GetClippingBox(), at the price of some extra complexity in wxDCImpl
itself, which seems to be worth it.
It's not possible to map the scaled integer coordinates to the exact
destination location. The inaccuracy can be (mostly) avoided by shifting
the DC origin instead. Also fixes handling of non-zero logical origin.
See #18129
Because wxDC can be the subject of geometric transformations (like translation, scaling) so we cannot assume in the calculations of the clipping box that DC origin is always at (0,0) and its logical size is the same as physical size. To get correct result we have to use logical coordinates of wxDC area in all clipping box calculations.
While setting a clipping box there is necessary to intersect it either with current clipping region location if such region exists or with wxDC surface extents if no clipping region is set. This way effective clipping box will be always inside the wxDC surface.
Note: Effective clipping box can be an empty region.

Windows CE doesn't seem to be supported by Microsoft any longer. Last CE
release was in early 2013 and the PocketPC and Smartphone targets supported by
wxWidgets are long gone.
The build files where already removed in an earlier cleanup this commit
removes all files, every #ifdef and all documentation regarding the Windows CE
support.
Closes https://github.com/wxWidgets/wxWidgets/pull/81
This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.

Get rid of the rest of __WXCOCOA__ tests in the sources.
Drop configure option for using it.
Also remove the documentation for this port.
This should have also been part of r76735.

It is not only useless with any modern C++ compiler, but also deprecated

This port is not used and is not being worked on, so remove it to reduce the

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 new private wxTextMeasure class implementing methods for measuring text
and move the often duplicated (but not always identically) code for doing the
same from wxDC and wxWindow into it.
Currently this class is only really implemented in wxMSW and wxGTK.
Also extend the test for text measuring functions and rename it to
MeasuringTextTestCase from MeasuringContextTestCase as it's not wxGC-specific
any more.
Closes#14705.

GetClippingBox() implementation relies on wxDCImpl::m_clip[XY][12] being
updated in DoSetClippingRegion() but this wasn't done here. Fix this by adding
the code to do this to the base class version of this method and calling it
from wxGtkPrinterDCImpl.
Also, refactor wxGCDCImpl to reuse the same code instead of duplicating it.
Closes#14697.

it.

wxWindow might not be fully declared in dcbase.cpp but we need its full
declaration for wxDCImpl::InheritAttributes() so explicitly include
wx/window.h -- while this is usually already included from somewhere else it
might not be in minimal builds with a lot of features disabled.

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.

Previously, wxUSE_STL enabled both implicit conversion of wxString to
std::[w]string and use of standard containers for the implementation of their
wx equivalents. Split up the two roles now by allowing to enable the use of
the standard containers independently of (backwards incompatible) implicit
conversion in wxString and actually enable wxUSE_STD_CONTAINERS by default.

Add a new wxDC method allowing to retrieve the font characteristics not
available from GetTextExtent(), notably the internal leading (and also the
average font width).
Currently this is implemented for wxMSW only, the internal leading is always 0
in the other ports.

Adjust the height of the underline to be compatible with native MSW behaviour.
Notice that in wxGTK we should use pango_font_metrics_get_underline_position()
to get the font-dependent value that should be used here.

Use doubles to avoid accumulated rounding errors from using integers in the
generic implementation of wxDC::GradientFillConcentric(). This results in
smoother gradient.
Also avoid using the expensive pow() function inside the inner loop when we
just need to calculate a square.

The selected colour was not used as the code simply changed the value of
m_pen but didn't call SetPen() to actually use it. This resulted in always
using the default (black) colour when drawing concentric gradients.
Fix this by calling SetPen().
See #12337.

No real changes, just use wxDCPenChanger instead of manual calls to SetPen()
in wxDCImpl::DrawPolygon(). This makes the code shorter and more clear.

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.

The old code stored the original colour of m_pen before changing it and
restored it on exit but this didn't work if the pen was invalid to start with.
Just store the pen itself instead, this works in any case.
