Why limit yourself to only one downscale level? Mipmap can go several
levels down, so it doesn't make much difference whether you started 4096 or
2048 (leaving space issues aside).
I suppose mipmaps aren't used for liveries in FG. What would be the cost
to do so? It doesn't sound right that every user should replace liveries
on their side to run MP, and one can't tell in advance what other aircrafts
she will encounter.
