* - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux
|

* - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)
|
||||
* - Mouse acceleration, there is no API in SDL yet for that
|
||||
* - Force relative mode in Grab mode even if SDL provides absolute coordinates?
|

* - Gamma tables support is likely to be broken here
|

* - Events processing is bound to the general emulation thread as SDL requires

* to PumpEvents() within the same thread as the one that called SetVideoMode().
