gdkevents-win32.c: Avoid crash in SetTimer()

+ - Forbid opening displays before gtk_init()
+
+* Gsk:
+ - Many improvements to the dmabuf downloaders
+ - ngl: Avoid glBufferSubData for globals, speeding up llvmpipe

+
+* Windows:
+ - Improve the backend code
+ - Fix some problems with WGL on NVidia
+ - Many testsuite fixes for Windows compatibility
