ruler coordinate system: scaling and offset
Hi,
I implemented an idea how to temporarily solve bug #170049 [1] for many users:
In short, I added scaling and offset for the ruler display and cursor position status display without affecting any of the internal coordinates. This allows to define an inverted coordinate system and does not need document versioning. However, precision might suffer and units are not saved in svg as they are displayed by the rulers.
Unfortunately, almost nobody seems to test this or give any feedback. I would appreciate to hear your opinion or have people test the patch.
Cheers, vaifrax
Think it could be very useful for example to retain artwork created previus to the future change of the coordinates system from the actual cartesian to the SVG standar, when finish my actual work i want to test your branch and feedback you.

This means it will cause the 'Transform...' dialog, X/Y/W/H spinboxes in the shape tools, and many other places that use desktop coordinates to show bogus values unrelated to the visible coordinate system.
This allows to define an inverted coordinate system and does not need document versioning. However, precision might suffer and units are not saved in svg as they are displayed by the rulers.
This adds an extra level of complexity that will make it harder to correctly fix the bug later on. Furthermore, it fixes only one part of the problem while leaving others broken and introduces inconsistency - this is far worse than the current situation, which is incorrect but at least consistent.
