[Web build] Mouse can be detected outside the screen about wasm4 HOT 3 OPEN

What would your preferred behavior be? Capping it out at zero / maximum screen size?

from wasm4.

Depends on the game. Different games might want different behaviors.

1. Keep events, clip to screen
2. Drop events when it's out (pico-8)
3. Drop events but last

Currently wasm4 differentiate between left/middle/right mouse button. This is unlike a physical touch screen.

About simulating physical touch screen, something needed: synthetic "touch down" event when mouse leave the screen while the button is held down. and "touch up" when mouse enter the screen.

Here's a game that heavily relies on mouse events outside of the canvas boundary: https://wasm4.org/play/future-avoid

It also happens to not be very playable on mobile because of that, but I guess that's a trade-off for game developers to decide. Maybe we can document it somewhere?
