It's always passed as nullptr. It's a good thing, too, since it looks like some of the implementations are returning a wrong pointer. Add some missing |const|s.

2018-08-13Implement CFX_CodecMemory.Lei Zhang
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().

2018-02-14Check that the request was satisfied in ReadDataRyan Harrison
Currently the BMP decompressor doesn't verify the returned data length was the amount requested. This means we may end up with part of our structure uninitialized if we didn't copy in enough data. This CL verifies the length of data copied is the size we require.

2018-02-13Change return value of GetAvailInputRyan Harrison
This changes the return value from uint32_t to FX_FILESIZE, which is the type the methods is uses return. The existing code does an unguarded static cast, so something like -1 could cause a very large value being returned. This change has a cascading impact up to the top of the progressive codec, which now has to handle negative values gracefully.
