The precision message depends on the gemwin dimen ?
If precision=1 then the texture size is the size of gemwin ?
If precision=2 then the texture size is the double size of gemwin ?

Why, the default is [antialias 1( ? Should be [antialias 0(, no ?
Because it will break patches...

Yep, crash here with [antialias 93(.
