I'm wondering though, should we make this setting the default choice? 
That's not the first time that NOT announcing larger texture support 
just causes trouble (quake4 not displaying any sky textures has the same 
reason), and I've yet to see that it causes trouble (i.e. a well-behaved 
app would query the maximum texture size, and be clever and use smaller 
ones, and with the allow large texture setting actually cause a raster 
fallback).
