Isn't this just MIT or something? How is this license different from more
standard ones?

It looks like a very very condensed version of the MIT license.
http://www.antigrain.com/license/ refers to it as "Anti-Grain Geometry Public
License" FWIW.

+        $license = "Anti-Grain Geometry $license";
+    }
+
     $license = "UNKNOWN" unless $license;
 
     # Remove trailing spaces.
     $license =~ s/\s+$//;
 
     return $license;
 }
 
 sub fatal($) {
     my ($pack,$file,$line);
     ($pack,$file,$line) = caller();
     (my $msg = "$progname: fatal error at line $line:\n@_\n") =~ tr/\0//d;
     $msg =~ s/\n\n$/\n/;
     die $msg;
 }
