More incremental work on getting touch commands on Android. I've pinpointed a nasty problem that looks possibly like a compiler bug - the float values that are passed into SDL_SendFingerDown() are coming out junk on the other end. Probably an extra push of something on the stack, as when I tried using pointers to floats instead, the y value showed up in the x position.
