commit 4039153ca793d5708d9dc9929b8cab29427f4bb7
Author: Philip Zander <philip zander gmail com>
Date: Tue Jul 28 20:22:30 2020 +0200
Rewrite GdkWin32Keymap (load table directly from layout DLL)
The old code used repeated calls to `ToUnicodeEx` to populate
the translation table, which is slow and buggy. The new code
directly loads the layout driver DLLs from Windows.
Associated issues: #2055 #1033
Merge request: !1051
GdkWin32Keymap cleanup

+ *
+ * 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

+ * - 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.
