Subject: [PATCH] Fix sticky camera rotate for touchpad navigation style on
 Windows (#8249)

* glcanvas: add modifiers to mouse events logging

* glcanvas: workaround for touchpad nav on Win

Releasing ALT on windows platform result in GLCanvas losing focus.
Because of this mouse movements not being processed by on_mouse() event
handler and camera rotation have not cleaned up.

Make a workaround for Windows to cleanup camera rotate state on
releasing ALT modifier.
