Fullscreen does not work

[mathstuf]

Currently the window disappears soon after appearing on Linux.

Inspection of the event queue shows this difference:

Dropping a window event: 1
Dropping a window event: 6
Dropping a window event: 5
Dropping a window event: 3
Dropping a window event: 10
Dropping a window event: 11
Dropping a window event: 3
Dropping a window event: 10
Dropping a window event: 6
Dropping a window event: 2
Dropping a window event: 7
Dropping a window event: 11

for fullscreen versus:

Dropping a window event: 1
Dropping a window event: 10

for windowed mode. It looks like SDL first creates and maps a window based on these events, but the "7" event indicates a minimize event coming through which I'm guessing is the reason it disappears. See http://wiki.libsdl.org/SDL_WindowEventID for the event table.
