Possible problem in tile engine

[Ed .]

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.

I decided to recompile Krita with the old tile engine, and sure enough, the problem disappeared.

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
