fix: Devices resolution and orientation issue

[Sesa1988]

Hi,

Description

I use a Android and a Windows device.
When I draw on the Windows device the screen and area is way larger.
When I open the saved scribble via JSON on my Android device I can not see everything drawn.
Is there a way to solve it? Maybe scrolling?

Steps To Reproduce

1.'Open app with scribble on large window device'
2. Draw on full area and save it
3. Open saved scribble from JSON on small device like a phone

This can also be reproduced by changing the device orientation without another device.

@timcreatedit Hi, do you think there is a workaround for this? Would be a cool feature to support. I am not sure what the best solution is but probably like scrolling?
