the original tiff

SUMMARY
When open a tiff file contain layers that have different sizes, it miss-aligned the layers: it does not respect the layer position instead it always put layers from (0,0)


STEPS TO REPRODUCE
1.  open given tiff file in krita compare with the result from gimp or imagemagick (`convert test-size.tiff -flatten test-size.im.jpg`)

OBSERVED RESULT
The `test` text is misplaced.

EXPECTED RESULT
The `test` text should be placed as the test-size.im.jpg

Amyspark, can you take a look?
Comment 4 amyspark 2022-10-01 00:09:48 UTC 
Thanks for the sample. I had noticed that Krita did not support TIFF layer positioning, so it'll be an interesting fix to make.
