.MIP files and developing a new tool

[CowtownBob]

1) I never found that, so things will work without changing it for each file, but it makes sense as a final step for if something is at such a far distance it shrinks to a single pixel.

2) The width of the original image is always a power of two, and each sub-image is half the previous, so yeah. On the height, make sure to round up - but when you do color recalculations, don't include the blank rows you add in.

3) Dunno.
