what should the default coordinate system be?
centred?
the coordinate system goes from 0-4096 in X and Y
It's preferable that drawing is centred around 2000
Let's offset the centre of the screen to 0 and draw natively from there
Let's apply a scaling factor which can increase coords
And a calibration/ warp
The aim is to be able to preview in any size window
