>How do I make a mipmapped version of the image map?
For a mipmapping level of n, process the original image with a mosaic
filter of size nxn and then downsample it to 1/n its original size
without any interpolation (nearest neighbour). This image will be more
suitable for larger distances as it provides more information in a
single screen pixel than the original version (a pixel of the rendered
picture, that is).
