Yes. The limit is whatever the driver announces, which is 256 if you've
got enough video ram (requires 64MB free texture space). Unless you
change the allow_large_textures option, that is (I don't want to
increase it to 512 since that's against the specced capabilities, plus
by default the driver would never announce support for it since it would
need 512MB free texture space).


The patch needs some cleanup before it can be applied.
