I had an ok week. The new tiled renderer is improved.
tiled renderer
The new image drawing system generally worked well! There were a couple of bugs, and it still has some limitations, but in general it really improved zoom and precache performance.
For the bugs, first of all, there was a rare crash, I think triggered by loading a very unlucky coincidence of tile and image size. Then clipboard bitmap copy threw an error, tiny images could not deal with extremely small zoom, and clients under heavy load could sometimes have trouble initialising the viewer. I have fixed them all, but let me know if you have any more trouble!
