I think we need to do an overall cleanup that clarifies what are UI coords, which are document coords, etc. The cleaner we can make this, the easier it will be to maintain and expand upon.
We just need to get rid of this artificial situation where what is shown in the UI does not match what is written into the document.
I definitely seen the need for a standard doc-to-ui transform that is configurable and dynamic. Among other things this will make it easy to have the document rotate as the ring on a wacom tablet is 'turned'. That's a very common bit of functionality that really helps artists.
This will be very hard to do, because the display system assumes the transformation from desktop to screen is a pure translate + uniform scale; the tiling system in SPCanvasArena is built on this assumption.
