[Screeninvader] html5 gamepad proof of concept

[Christian Sl]

hi,

a proof of concept is already working, i can control the mouse with my usb gamepad and send the mouse position
via screeninvader.js to the invader.
unfortunately as it is it's not really usable, only being able to position the mouse with absolute coordinates
makes it rather difficult to use. would it be possible to add relative mouse positioning
to the screeninvader lua mouse script?

kind regards, christian
