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.
39	+	* - Backport hw cursor acceleration to Basilisk II?
40	+	* - Factor out code
