+    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
