This function is not present in older MinGW import libraries, up to at least
MinGW 4.8.1, so we can't use it directly as it was done in
22f0801378 and we need to load it dynamically.
This was already done in wxDC code, so just reuse the same wrapper function
after extracting it (and a few others, for consistency) into a new header.
This reverts commit d04e256993 because it
results in crashes due to writing out of bounds of the bitmap: nothing
guarantees that the entire (x, y, dstWidth, dstHeight) rectangle fits in the
destination bitmap and so the code of this commit could merrily overflow it
and did it as could be seen e.g. in the HTML test sample after scrolling
around a little.
See #16766.
Don't erase alpha channel of the entire destination image after drawing on it
using AlphaBlend(), we only need to do it for the area corresponding to the
bitmap drawn on it. This speeds things up when drawing small bitmaps with
alpha on a big bitmap without alpha selected into wxMemoryDC which is a common
case.
See #16766.
Reset pointers to functions loaded from msimg32.dll when the library is
uninitialized as they may change if it's re-initialized again and msimg32.dll
is reloaded at a different address.
Also do the same thing for the function pointers from gdi32.dll for
consistency, even though it doesn't seem to be actually required in this case.
Closes#17167.
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
Don't mix signed/unsigned integers in arithmetic operations when normalizing
wxDC scale factors: variable holding GCD value should be of the same type as
variables holding devExt and logExt to avoid wrong results of /= operation
when dividend is a negative value.
Closes#16908.
Add helper wxApp::MSWGetDefaultLayout() static method and use it instead of
wxTheApp->GetLayoutDirection() in wxMSW code.
This serves two purposes: first, wxMessageDialog doesn't crash when it's shown
before wxTheApp is created (or after it's destroyed) any more. And second, we
use the correct layout direction if the main application has enabled it by
calling SetProcessDefaultLayout() or using two U+200E characters in the
beginning of its "FileDescription" resource field by default now.

This reverts r78040 (see #16512) as it broke the appearance of the disabled
buttons in MSW toolbars as can be seen in the sample.
The change itself might still be correct and could have just uncovered some
other bug elsewhere, but for now still revert it just to make the toolbars
usable again.

This partially reverts the changes of r77029 and r77039: now functions such as
Set/GetLayout(), AlphaBlend() and GradientFill() are still called (almost)
directly when using MSVC but pass by dynamic loading with the other compilers,
which don't have #pragma comment(lib) and, in MinGW case, also lack some of
these functions in their libraries even if we do link with them.
Closes#16411.

Implicitly link msimg32.lib in when using MSVC and add it to MinGW (and

This compiler is not being developed since several years and almost certainly
can't be used to build the current wxWidgets sources anyhow, so remove all
support for it, including a lot of extremely ugly workarounds for its bugs
with template functions.

Avoid passing source HDC to MaskBlt() for these ROPs which only use the

Make DrawIcon() work when printing: it previously didn't, as we used
::DrawIconEx() Windows function which wasn't supported when printing.
Work around this by using DrawBitmap() if necessary.

Explicitly reset wxBitmap alpha flag after clearing its alpha channel to
ensure that we don't treat it as having alpha after going to all the trouble
of ensuring that it doesn't/

Previously, the area of the bitmap outside of the rectangle covered by the
bitmap being drawn became completely transparent, "losing" the original bitmap
contents. This was due to some pixels of the bitmap having non-0 alpha value
after AlphaBlend() call, as it updates both the colours and alpha of the
destination. As there doesn't seem to be any way to prevent it from doing
this, just reset alpha back to 0 after calling it to avoid the problem.
Closes#14403.

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.

Use wxMSW::GetLayout() wrapper to avoid directly binding to a function not
present in old Windows versions and also to fix linking errors with MinGW

The mask must be mirrored in the same way as the main bitmap itself (currently
it's not mirrored at all but this could change in the future), so create the
temporary memory HDC with the same layout as is used by the main HDC.

It wasn't there before wxTextMEasure changes and it doesn't seem obvious why
should it be there, it should be possible to measure the text using the
default wxDC font without setting one explicitly.

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.

Use t_str() instead of wx_str() to make the code work correctly in UTF-8 build

It turns out that the changes r71028 were unnecessary (and actually harmful)
in most cases, they're only needed when a DIB is used as a source DC. So move
the manual coordinates adjustments to the branch of code using StretchDIBits()
and don't do it anywhere else.
Also don't list this as an incompatible change as wxMSW actually already
worked as the other ports in the majority of cases and list it as a simple bug
fix instead.

Use the maximal device space extent supported by Win32 GDI and only decrease
it if the scale is so small that keeping the device space extent maximal would
result in overflowing the int range for the logical space.
This makes coordinate translations exact even for huge coordinates, while they
could be significantly wrong before due to the integer rounding errors.

Notice that this commit doesn't really change anything, in particular it
doesn't correct zooming for zoom factors that are power of 2 (which was broken
before as ticket #11669 showed), this was already done by the previous commit.
This one simply makes multiplying by VIEWPORT_EXTENT a tiny bit more efficient.
See #9554.

Multiply by scale factor when it's > 1 and divide by it when it's < 1 to avoid
rounding errors. By choosing whether to increase the viewport or window
extents we increase precisions without any apparent negative effects (at least
under Windows NT where the coordinates in 2^27 range are supported, but even
under Windows 9x it's not clear if the old code was better as while we never
overflowed the viewport extents, we could overflow the window ones easily for
small zoom factors).
