22   *  NOTES:
23   *    The Ctrl key works like a qualifier for special actions:
24 < *      Ctrl-Tab = suspend DGA mode
24 > *      Ctrl-Tab = suspend DGA mode (TODO)
25   *      Ctrl-Esc = emergency quit
26   *      Ctrl-F1 = mount floppy
27   *      Ctrl-F5 = grab mouse (in windowed mode)
28   *
29   *  FIXMEs and TODOs:
30 + *  - Windows requires an extra mouse event to update the actual cursor image?
31 + *  - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux
32   *  - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)
33   *  - Mouse acceleration, there is no API in SDL yet for that
34   *  - Force relative mode in Grab mode even if SDL provides absolute coordinates?
33 *  - Fullscreen mode
35   *  - Gamma tables support is likely to be broken here
36   *  - Events processing is bound to the general emulation thread as SDL requires
37   *    to PumpEvents() within the same thread as the one that called SetVideoMode().
38   *    Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
38 *  - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
39   *  - Backport hw cursor acceleration to Basilisk II?
40 + *  - Factor out code
