More or less. We have tests that show that setting a fullscreen / exclusive
cooperative level shouldn't mess with the window styles. E.g.
test_window_style() in ddraw/tests/ddraw7.c. We also have tests that show that
switching to fullscreen does have an effect on e.g. window dimensions, z-order
and focus.

The proper mechanism for communicating with the user / GL driver is probably a
WGL extension, somewhat similar to how we currently have
WGL_WINE_pixel_format_passthrough for resetting the pixel format. (Although
that specific extension has some issues.)
