While working on the perspective transformation tool I noticed that when transforming \
the image, the region of the upper left corner of the image went missing. After \
discussing the problem with CyrilleB, he noticed that the size of missing part was \
64x64, which happens to be the size of a tile in the tile engine.<br>


<br>
I decided to recompile Krita with the old tile engine, and sure enough, the problem \
disappeared.<br> <br>
It would be a good idea for someone with knowledge in this area to look into this. \
The relevant perspective code is in \
krita/plugins/tools/tool_perspectivetransform/kis_perspectivetransform_worker.cpp<br> \
