From 4816432671eef6467354aa252f22bb80acc315b7 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Tue, 20 Oct 2015 13:19:19 -0400 Subject: Add type cast definitions for CPDF_Dictionary. This CL adds ToCPDFDictionary type definitions and updates one file to use instead of straight casts. I had to fix two places where we'd casted off the constness of the original pointer.
