+// Notes (http://lists.apple.com/archives/java-dev/2006/Apr/msg00588.html):
+// There are three main types of PICT files:
+// - Version 1
+// - Version 2
+// - Extended Version 2
+//
+// Some things to look out for:
+// - The bounds and target DPI are stored in a different place in all three.
+// - Some of the values are fixed-point shorts ( short / 65536f )
+// - Values are big endian
+// - All of this may be *preceded* by a 512 byte header--sometimes it is
+// there, and sometimes it isn't. You just have to check for the magic
+// values in both places.
