Old Evans&Sutherland image generators didn't have MIPmapping and used
'contrast clamping' to manage aliasing - it didn't work all that well,
but it was certainly better than doing nothing.  They altered the texture
contrast as a function of range and orientation.

I'm not sure that helps.

Yes please.

There *are* cases where disabling MIPmapping and linear-blending is
useful though (the Icons on the bottom of the TuxKart screen and
the text in PLIB/FNT are two examples).
