SUMMARY
If there is a vector object which spans beyond the canvas boundary , and a user converts it to raster (paint layer) the content that is beyond the canvas boundary gets trimmed or cropped.

STEPS TO REPRODUCE
1. Open krita add a new vector layer, draw a rectangle such that half of it is beyond canvas boundary
2. right click on the layer in layer stack and go to convert > to paint layer
3. check the resulting layer by moving it, it must be now trimmed, discarding the portion that was out of canvas

OBSERVED RESULT
the vector objects beyond the canvas get trimmed when converting to paint layer

EXPECTED RESULT
the data should be preserved even when converting to paint layer
