That means messing around with the mysterious and arcane Xlib...

SDL_CreateCursor() is unfit to do this, another different function will be
needed: either this function does not yet exists or is not documented.
I need also to use SDL 1.2.4 since 1.2.5 complains my ALSA drivers are too
old (they're from Debian stable... i don't think they're SO that old...)

Maybe you're right... even if i'll have to lose weeks just to understand how
to get a 800x600 window... =(
Most of X11 tutorials focus on GUI, while i need a way to draw a linear
bitmap on the screen (X11 pixmaps need to pass through X server and are
unlikely to give 30 refresh per second...), read from mouse and read from
keyboard: no buttons, sliders, captions, sub-windows and like...
