texture dimension limits in ddx
in nv10_exa.c :
check_texture does :
if (w > 2046 || h > 2046)
NOUVEAU_FALLBACK("picture too large, %dx%d\n", w, h);
check_render_target does :
if (w > 4096 || h > 4096)
return FALSE;
So we have different size limits for the source and the destination ?
Another thing is that nv20 uses nv10_exa.c code, and the limit in
