From Patrice Mandin: "Just a request about test subdirectory: the autotools files (config.guess, config.sub, etc...) are a bit outdated, and I have to update them for my cross-compilation party. So it would be nice to have these updated. ... Just removing these files works, because then configure will use those of SDL's topdir. Could someone else check this, just to be sure? i.e. remove config.guess, config.sub, install-sh and mkinstalldirs from test subdir." I tested on Linux and MacOSX...seems to be safe, so I'm nuking the files. --ryan.

>A <TT
CLASS="LITERAL"
>SDL_JOYBALLMOTION</TT
> event occurs when a user moves a trackball on the joystick. The field <TT

><I
>which</I
></TT
> is the index of the joystick that reported the event and <TT
CLASS="STRUCTFIELD"
><I
>ball</I
></TT
> is the index of the trackball (for a more detailed explaination see the <A
HREF="joystick.html"
>Joystick section</A
>). Trackballs only return relative motion, this is the change in position on the ball since it was last polled (last cycle of the event loop) and it is stored in <TT
