and Voodoo cards up to Voodoo3 had a maximum texture size of 256.

this is a hw limitation, and in general the hw capabilities of each card
should be queried before assuming "it just works".

there also might be hw with min texture size limitations, as in an old
Matrox ( iirc ) card had a min texture size of 8x8 so it couldnt do
mipmaps down to 1x1.

speaking of mipmaps, there can be issues if the texture isnt square, eg
128x256 instead of 256x256. in that case mips might have to stop when
the 1st 1x size in either dimension is reached.
