I think the miscolored fields and cyan roads is the same problem: the
lowest level mipmap image appears in the wrong color.  For the fields,
the color is black while the roads are usually cyan, but not always.
Daryll and I have both looked into this but haven't found the cause.

I think Harry's problem is different.  it sounds like a bug reported
by Loki in which the wrong textures are bound in some cases.

I'm hoping to look into that problem this month.
