Subject: SDL 1.2.7 patch for BeOS (new input handling code)
I rewrote input handling code for BeOS. It should be faster now (i got
report that mouse is faster, keyboard should be too, but it's harder to
observe).
I'll try to add mouse wheel support too, soon.
Stefano Ceccherini (a.k.a Jack Burton) helped me beautify code (working
version was less clean), and it was he who asked me to write this thing ;).
