Attached is a patch that enables Xinput2 API for processing mouse-movement. No new functionality is implemented.
Notes: -I refactored/moved the x11 touch input setup stuff since it also gets used for the mouse -touchpad events were implemented in Xinput 2.1, but touchscreen events are in ver 2.2 I simply made 2.2 the minimum requirement. I don't think it's worth it to test for both versions and it seems to be what other projects (eg: GTK) are doing. Important: Xorg apparently does not allow using both the legacy API and Xinput2 for the same event class. So enabling listening for XI_Motion events causes the MotionNotify events to stop. Hence, this patch _only_ grabs the mouse-movement events in Xinput2 so that allegro has access to touchpad events we can add later in the future. All other inputs + window + mouse events are all still being handled by the legacy API. Testing: - allegro5 builds with and without xinput2 support - mouse example programs and ALLEGRO_MOUSE_EVENT members all work for legacy and XInput2 versions. - pointer and mouse-wheel acceleration work for mouse and touchpad - hot-plugging USB mouse works and simultaneous use with touchpad works Everything behaved as expected for me. Please review and consider for addition. Thanks, Pho75
