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.
