+There is no bug in the codec signature decoding :|
+
+The WMF without an Aldus placeable header shouldn't be detected by
+GDI+ as it's header doesn't match the signature(s) of any codec.
+However it is, somehow, detected as a EMF metafile (but it's a 16bits
+WMF). Even more messed up is that the image can still be displayed
+correctly (so the headers are obviously not used).
+
+This isn't the first time that the "correct" and "published" headers
+information diverges. I may have to duplicate headers so we return MS
+GDI+ compatible values while we use "valid" values to process metafiles.
+
+All this is probable due to the fact that GDI+ doesn't do itself a lot
+wrt metafiles (and even less correct stuff) and only delegates that
+stuff at GDI. However that doesn't explains codec signature mishandling :|
