Sometimes the file dialog changes the current directory even if it is
cancelled, so restore it in any case, not only after successful return.

When Cairo surface is created from 32bpp wxBitmap then there is necessary to provide a location of its bit values to cairo_image_surface_create_for_data function and hence bitmap selected into wxMemoryDC has to be converted to DIB, if it is not a DIB already.
Moreover, if 32bpp bitmap doesn't contain real transparency data (is 0RGB bitmap) then its alpha values have to be corrected and set to wxALPHA_OPAQUE value (255).
Closes#17469.
Return the size of the entire virtual screen, possibly composed from multiple
monitors, rather than just the size of the primary monitor.
This makes this method consistent with wxScreenDC actually representing the
entire virtual screen and not just the primary monitor and also with wxGTK.
Closes#13279.
Scintilla conversions use UTF-16, as indicated by their names, while wxString
uses UTF-32 under Unix, so they don't work correctly for the characters
outside of BMP.
Simply use our own UTF-8 conversions, it doesn't seem possible to get invalid
UTF-8 sequences here anyhow, so the comment saying that Scintilla functions
are used to avoid asserts doesn't seem to be relevant.
Closes#15621.
The function such as fn_str(), wc_str(), and ToAscii() have
configuration-dependent return types, yet different variants were claimed to
be member function overloads. This is incorrect, as a member function cannot
be overloaded only by its return type and, for any given platform/build
variant only one of them is available.

32bpp wxBitmaps selected into wxMemoryDC can represent either 0RGB or ARGB bitmaps and hence there is necessary to instruct renderer how to interpret 32bpp contents while creating a wxGraphicsContext. wxBitmap::HasAlpha() flag is used for these purposes and its value is passed to wxD2DContext ctor (wxD2DContext is used internally as a backend D2D component) and next used to configure physical renderer created with ID2D1Factory::CreateDCRenderTarget.
Closes#17465.
cairo_surface_create_similar_image() introduced by the changes of
d6afb66388 is only available in 1.12 and later,
check for it being available and fall back to cairo_surface_create_similar()
with older versions.
This should fix Travis CI builds.
Not onlu has Scintilla no support for RTL languages, it is rendered into
a mirrored DC on Windows and so guaranteed unreadable and unsable. Fix
it by explicitly setting the window's layout direction to LTR.
Fixed creating wxCairoBitmapData from 32bpp wxBitmap (with and without alpha channel). This also fixes wxCairoRenderer::CreateBitmap method.
1. 32bpp bitmap can represent under MSW either ARGB or RGB bitmap so there is necessary to examine its real contents with wxBitmap::HasAlpha function.
2. ARGB bitmaps are premultiplied and there is not necessary to premultiply them again.
There is nothing we can do about these (harmless) warnings, so just
disable them. Also make sure that the header is included via
wx/msw/wrapshl.h everywhere.
Expand() called ExpandAncestors() in the generic wxDataViewCtrl implementation
but not in the native ones, resulting in observable difference in the
behaviour: for example, the wxDataViewTreeCtrl in the dataview sample appeared
initially expanded under MSW, using the generic version, but collapsed under
GTK and OSX.
Harmonize this among all ports. This also has a nice side effect of making
Expand() less horribly inefficient as it is not recursively called by
ExpandAncestors() which it itself used to call: now ExpandAncestors() only
calls DoExpand() which is a simple function that only expands the item passed
to it and does nothing else.
Closes#14803.
The code handling background colour was commented out for some reason, simply
enable it as it seems to be working just fine -- and update the sample to show
that it does.
The check added in 841af56084 was not good
enough, some MinGW versions do have imagehlp.h, but don't define all the API
functions we need in it. Luckily, we can check for this simply by verifying
that API_VERSION_NUMBER is big enough.
Closes#17451.
There is no need to handle Carbon port any more, so simplify the script and
just append the Cocoa-specific tags to the main tags file instead of creating
another one.
Refresh(&rect) was used instead of Refresh(true, &rect) mistakenly, thanks to
clang for warning about always-true-conversion-to-bool here.
Fix this by using less error-prone and more clear RefreshRect().
