Upstream commit 713c3f9d1b10ac25fb3c4a1ff115e23c035851dba from the wx
master branch (3.1.x).
Fixes the crash when the current language is Korean and the Change
Language dialog is accessed.
WS_POPUP causes fullscreen tearing when using OpenGL and the GSPanel
rendering area exactly covers the full screen. (always affects stretch
mode, but most people have 16:9 monitors, so in general the widescreen
16:9 mode is also affected).
Fixes#1075
There was a version check in the menu handling, but Windows 8.1 and
Windows 10 weren't recognised and some pre Windows 98 code was used.
This is a combination of the following wxWidgets upstream commits.
