Sam Lantinga df5898b0d3 Fixed bug 3464 - Fix for Android hint SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH 
ny00

According to the current documentation in SDL_hints.h, if SDL_HINT_ANDROID_SEPARATE_MOUSE_AND_TOUCH is set to "0" (or not set at all) then mouse input should lead to touch events, along with corresponding *fake* mouse events with mouse id SDL_TOUCH_MOUSEID.

However, while moving a mouse around (actually using a trackpad identified as a mouse), I get SDL mouse motion events with differing mouse ids, as follows:
- If the mouse is moved while a mouse button is pressed, the mouse id is SDL_TOUCH_MOUSEID.
- Otherwise, the mouse id for mouse motion events is 0.

I've attached sample code for reference, which includes logs of the various mouse events (the "which" field is covered).

I believe that no actual mouse event should arrive, if the hint is unset. In particular, no mouse motion event should arrive while no mouse button is pressed.

I'm going to attach a patch which resolves this, while also disabling mouse wheel motion events.

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
with README.md

Enjoy!
