Fix chunk/pixel alignment

Browse Source 
- Adjust coordinates, so that chunks are always in the center of the window
- Modify VIRTUAL_RESOLUTION_OFFSET_X/Y to match window output with expected coordinates
- Fix black line at the bottom of window
- Remove tile bleed/inset while stitching, as it is not needed anymore
