-% Form caching implemented in PostScript.

-% This implementation doesn't do the right thing about halftone or
-% Pattern phase, but the Pattern cache doesn't either....
-
-% The Form cache key is the Form dictionary; the value is an array
-% of 2 elements [CTM pattern_instance].
-%
-% In order to prevent restore from clearing the cache, we explicitly
-% push the cache entries on the stack before a restore and reinstall them.
