I had an ok week mostly working on making images look better.
warped tiles
tl;dr: Images look better now.
I put a lot of time into the tiled renderer this week, mostly fixing 'stretch-warped' tiles. These are most obvious in the duplicate viewer when you are flipping between two very similar images that have slightly different resolution--you would see one part of one of the images stretched one pixel horizontally or vertically compared to the other.
