[SDL] Precision of mouseX/mouseY in Touch events

For some reason, the X/Y coords of Touch related events (down/up/move) are 0-100 based. This is incredibly low for any modern screen.

Is it possible to use actual screen coords or at least a much higher precision range here?

Is the input range 0-1 ? If yes then yes it should scaled by something like 65536 Maybe requires some changes on Heaps side as well.

Yes base value is 0-1 according to SDL api. Isn't it possible to match the actual context size, as expected for a mouseX/Y value?

I have no idea, it was originally contributed as part of native mobile support in #101 (ping @rtissera)

It's been increased to 10000 since then.
