Width and height were exchanged in the loops, so the conversion code didn't
work correctly and overflowed the pixel buffer (due to extra padding in the
row stride) for non-square bitmaps. It also resulted in a completely wrong
bitmap appearance, but somehow this managed to go unnoticed, unlike the memory
errors.
Closes#17633.
1. Override wxWindow::GetContentScaleFactor() to use gdk_window_get_scale_factor()
when available, and to use correct scale (1.0) otherwise, as wxDC::GetPPI()
(used by overridden method) is not properly implemented for wxGTK
2. Record scale in wxBitmap(wxImage&) ctor and wxBitmap::CreateScaled()
3. Adjust cairo scale for drawing bitmap, and (inversely) for drawing on bitmap
Homogenize the behaviour of all ports when creating bitmaps with 0 width or
height: just fail always as it doesn't seem to make sense to support this.
Closes#16828.

And don't use "RootWindow" in the name, it is not a root window in the X11 sense.
Also add wxGetPangoContext() to get access to a PangoContext.

Drawing on a wxBitmap via wxMemoryDC modified its pixmap representation in
wxGTK and even if its pixbuf representation was later changed using direct
access to the bitmap pixels, the out of date pixmap continued to be used,
creating the illusion of direct access being completely ignored.
Fix this by purging the old pixmap representation when locking the bitmap for
raw access.

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.

When building wxGTK under MSW, always use UTF-8 as file name encoding because
GTK+ doesn't use G_FILENAME_ENCODING there.
Add a helper wxGTK_CONV_FN() macro to hide the difference between the
platforms.

wxBitmapRefData didn't have a proper copy ctor but the code in wxGTK wxBitmap
implementation used it nevertheless and then manually patched the newly copied
object to avoid double pointer deletion and other unpleasantness.
Make the code more obviously correct by not using (nor providing) copy ctor at
all. There are no real changes otherwise.
See #12768.

No real changes, just add some wxUnusedVar() to avoid warnings about
parameters unused in some non-default build configurations.

There are no real changes in this commit but it removes all trailing white
space from our source files. This avoids problems when applying patches and
making diffs and it would be nice to prevent it from reappearing.

Without copy ctor copying masks simply crashed because the same pointer was
deleted twice.
Also added a (completely trivial but better than nothing...) unit test for
wxBitmap to check that copying masks does work now.

1. remove UseAlpha() on platforms that don't need it and call it automatically from ~wxPixelData instead of requiring explicit call; deprecate wxPixelData::UseAlpha()
2. don't call UngetRawData() if GetRawData() failed

1. perform deep comparison for the classes for which it makes sense in the
ports where this wasn't done yet
2. remove (shallow) comparison operators for the classes for which it does
not make sense (such as wxBitmap)
3. makes wxBitmap use COW on all ports
4. adds wxObject::IsRefTo()
5. centralizes and improves COW docs
