In the direct and redirect phases, tiles are read from the backing image server and send forward to the GUI. This is currently done through the Java image frameworks, which means a lot of cycles wasted on decoding and encoding images, including quality loss due to JPG.

Such tiles should be handled outside of the image framework.

For the redirect phase, served tiles must be square. This makes it problematic to pass-through as some edge-tiles must be padded. Maybe issue #11 can help here, as it can be calculated whether a tile will be full-sized or partial.
