containers that can be scrolled should have precedence

over child widgets that also react to scrolling like GtkComboBox, GtkScale and GtkSpinButton, because otherwise when you're in the middle of scrolling the view/window you can involuntarily scroll over the widgets and change its values. This problem can be seen in applications like pavucontrol, gnome-tweaks prefs, devhelp prefs, and so on. Fixes issue #3092

 building with Visual Studio 2008 or later is supported, either via Visual Studio

+For Visual Studio 2008, 2010, a special setup making use of the Windows 8.0 SDK
+is required, see at the bottom of this document for guidance.
 Interchanging between Visual Studio 2015, 2017 and 2019 builds should be fine
 as they use the same CRT (UCRT) DLLs.

@@ -286,6 +288,73 @@ If you are building with Visual Studio 2008, note the following items as well:
 - The more modern visual style for the print dialog is not applied for Visual
  Studio 2008 builds.  Any solutions to this is really appreciated.

+Support for pre-2012 Visual Studio
+==================================
+
+This release of GTK+ requires at least the Windows 8.0 SDK in order to be built
+successfully using Visual Studio, which means that building with Visual Studio
+2008 or 2010 is possible only with a special setup and must be done in the
+command line with Ninja.  Please see
+https://devblogs.microsoft.com/cppblog/using-the-windows-software-development-kit-sdk-for-windows-8-consumer-preview-with-visual-studio-2010/
+for references; basically, assuming that your Windows 8.0 SDK is installed in
+`C:\Program Files (x86)\Windows Kits\8.0` (`$(WIN8SDKDIR)` in short), you need
+to ensure the following before invoking Meson to configure the build:
+
+- Your `%INCLUDE%` must not include the Windows 7.0/7.1 SDK include directories,
+  and `$(WIN8SDKDIR)\include\um`, `$(WIN8SDKDIR)\include\um\share` and
+  `$(WIN8SDKDIR)\include\winrt` (in this order) must be before your stock
+  Visual Studio 2008/2010 header directories.  If you have the DirectX SDK installed,
+  you should remove its include directory from your `%INCLUDE%` as well.
+- You must replace the Windows 7.0/7.1 SDK library directory in `%LIB%` with the
+  Windows 8.0 SDK library directory, i.e. `$(WIN8SDKDIR)\lib\win8\um\[x86|x64]`.
+  If you have the DirectX SDK installed, you should remove its library directory
+  from your `%INCLUDE%` as well.
+- You must replace the Windows 7.0/7.1 SDK tools directory from your `%PATH%` with
+  the Windows 8.0 SDK tools directory, i.e. `$(WIN8SDKDIR)\bin\[x86|x64]`.
+  If you have the DirectX SDK installed, you should remove its utility directory
+  from your `%PATH%` as well.
+
+The Windows 8.0 SDK headers may contain an `roapi.h` that cannot be used under plain
+C, so to remedy that, change the following lines (around lines 55-57):
+
+  // RegisterActivationFactory/RevokeActivationFactory registration cookie
+  typedef struct {} *RO_REGISTRATION_COOKIE;
+  // RegisterActivationFactory/DllGetActivationFactory callback
+
+to
+
+  // RegisterActivationFactory/RevokeActivationFactory registration cookie
+  #ifdef __cplusplus
+  typedef struct {} *RO_REGISTRATION_COOKIE;
+  #else
+  typedef struct _RO_REGISTRATION_COOKIE *RO_REGISTRATION_COOKIE; /* make this header includable in C files */
+  #endif
+  // RegisterActivationFactory/DllGetActivationFactory callback
+
+This follows what is done in the Windows 8.1 SDK, which contains an `roapi.h`
+that is usable under plain C.  Please note that you might need to copy that file
+into a location that is in your `%INCLUDE%` which precedes the include path for the
+Windows 8.0 SDK headers, if you do not have administrative privileges.
+
+Visual Studio 2008 hacks
+========================
+
+- You need to run the following lines from your build directory, to embed the
+  manifests that are generated during the build, assuming the built binaries
+  are installed to `$(PREFIX)`, after a successful build/installation:
+
+```cmd
+> for /r %f in (*.dll.manifest) do if exist $(PREFIX)\bin\%~nf mt /manifest %f (PREFIX)\bin\%~nf;2
+> for /r %f in (*.exe.manifest) do if exist $(PREFIX)\bin\%~nf mt /manifest %f (PREFIX)\bin\%~nf;1
+```
+
+
+- If building for amd64/x86_64/x64, sometimes the compilation of sources may seem to hang, which
+  is caused by an optimization issue in the 2008 x64 compiler.  You need to use Task Manager to
+  remove all running instances of `cl.exe`, which will cause the build process to terminate.  Update
+  the build flags of the sources that hang on compilation by changing its `"/O2"` flag to `"/O1"`
+  in `build.ninja`, and retry the build, where things should continue to build normally.

+/* This is our equivalent of the KBD_LONG_POINTER macro in Microsoft's kbd.h.
+ *
+ * A KBD_LONG_POINTER represents a pointer native to the *host*.
+ * I.e. 32 bits on 32-bit Windows and 64 bits on 64-bit Windows.
+ *
+ * This is *not* the same as the the bitness of the application, since it is
+ * possible to execute 32-bit binaries on either a 32-bit *or* a 64-bit host.
+ * On a 64-bit host, KBD_LONG_PTR will be 64-bits, even if the application 
+ * itself is 32-bit. (Whereas on a 32-bit host, it will be 32-bit.)
+ *
+ * For clarity, here is an overview of the bit-size of KBD_LONG_POINTER on all
+ * possible host & app combinations:
+ *
+ *      Host  32  64
+ *  App +-----------
+ *  32  |     32  64
+ *  64  |     -   64
+ *
+ * In the official MS headers, KBD_LONG_POINTER is implemented via a macro
+ * which expands to the attribute `__ptr64` if the keyboard driver is 
+ * compiled for a 64 bit host. Unfortunately, `__ptr64` is only 
+ * supported by MSVC. We use a union here as a workaround.
+ *
+ * For all KBD_LONG_POINTERs, we define an alias starting with "KLP".
+ * Our naming schema (inspired by the Windows headers) is thus the following:
+ * - FOO:    The type FOO itself
+ * - PFOO:   Regular pointer to the type FOO
+ * - KLPFOO: Keyboard Long Pointer to the type FOO

+/* IMPORTANT:
+ *
+ * Keyboard layout DLLs are dependent on the host architecture.
+ *
+ * - 32 bit systems have just one 32 bit DLL in System32.
+ * - 64 bit systems contain two versions of each layout DLL: One in System32
+ *   for 64-bit applications, and one in SysWOW64 for 32-bit applications.
+ *
+ * Here comes the tricky part:
+ *
+ * The 32-bit DLL in SysWOW64 is *not* identical to the DLL you would find
+ * on a true 32 bit system, because all the pointers there are declared with
+ * the attribute `__ptr64` (which means they are 64 bits wide, but only the 
+ * lower 32 bits are used).
+ *
+ * This leads to the following problems:
+ *
+ *   (1) GCC does not support `__ptr64`
+ *   (2) When compiling the 32-bit library, we need two versions of the same code
+ *       and decide at run-time which one to execute, because we can't know at
+ *       compile time whether we will be running on a true 32-bit system, or on
+ *       WOW64.
+ *
+ * To solve this problem, we generate code for both cases (see
+ * gdkkeys-win32-impl.c + gdkkeys-win32-impl-wow64.c) and encapsulate
+ * the resulting functions in a struct of type GdkWin32KeymapImpl,
+ * allowing us to select the correct implementation at runtime.
