It will be used for steering on Android.
There are some limitations:
- currently it works only in single player mode (but I don't see any reason to make it working for multiplayer)
- speedometer is not available in race GUI because there is no place for it
TODO:
- add DPI support (race GUI should have probably different proportions on smaller devices for comfortable playing)
- make nice button images
- make nitro button that changes its look depending on collected nitro (a kind of nitro bar)
Touch input events must be handled in android device to make use of it. It can be simulated for debugging on non-android devices using standard mouse.
