2 Level downsampling on a true 16:10 res #198

3840x2400 downsamples to 3160x2100 first and then to 1680x1050.

This is bad because:

  1. Take a huge framerate dip from the double rendering
  2. 3160x2100 is not a true 16:10 and has black bars on the sides 2.5 Anything in the black bars will infinitely stay there so if you have a frame rate counter on any of the black bars they will stack on top of each other infinitely and "down" will always be on the top left corner. It is pretty distracting.

This two level downsampling is odd, I don't understand what the point of it is, and it kind of defeats half the reason for you use Lanczos too, as lanczos benefits from having more pixel information so it can weigh their influence to maintain a sharp image.
