Screenshots: Original 4K Monitor Left and 1920x1080 Right

SUMMARY
A saved *.kra file text is resized/repositioned if the file is opened when the computer monitor resolution differs from the resolution of the monitor used when the file was created (originally saved).  This problem appears to affect vector graphics as well  

STEPS TO REPRODUCE
1. Create and save a *.kra containing text as normal with a 4K monitor.
2. Close Krita and replace the monitor to one with a lower resolution.
3. Open the saved *.kra file.

OBSERVED RESULT
The text is resized and repositioned.  This is an issue when opening saved *.kra files on different computers.  The *.kra has to be edited for each computer individually.

EXPECTED RESULT
The relative position and size of text should remain constant and not change due to the monitor resolution.
