From b4a261855b34b4c8d938118762ae609a34a3ae99 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Wed, 1 Mar 2017 12:15:00 -0800 Subject: Create virtual codec APIs so chrome/fuzzers can link separately The one step to make an actual concrete class is conditionalized in fpdfview and is unconditional in the fuzzer. Also replace the clumsy C-style callbacks with a delegate interface as long as we are making new interfaces.
