I thought of mentioning this quirk but I didn't, sorry.  I found it equally confusing.

It would be good to have a way to ask SDL to not give emulated mouse events on a touchscreen...  Because for example one might really have a mouse AND a touchscreen (macbook) and one to distinguish 
the two.

SDL 1.3 iOS generates mouse and finger on finger events.

Android generates mouse on finger events (I need to fix this, need to implement the jazzhand feature).

I just could not figure out why everything was so jumpy :)  Is this by design?  It's easy enough for me to #define out the mouse stuff, but that doesn't really seem right.
