From d801c9c9caddf3941f6844fab58b19261d7d3cad Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Mon, 13 Aug 2018 20:36:16 +0000 Subject: Implement CFX_CodecMemory. This class is much simpler than CFX_MemoryStream and does only what CFX_BmpDecompressor and CFX_GifContext needs. Swap out CFX_MemoryStream and remove CFX_MemoryStream::Seek().
