I was wrong about the subblock lengths, the GIF spec requires them to have specific lengths.
This removes collecting whole extension data into
ext.data. The data now holds only a single subblock at a time, so it never reallocates. TheStreamingDecoderis streaming the extensions.Parsing of extensions is moved to the higher-level
Decoder. Thanks to this, it doesn't have to copy/reallocate XMP or ICC data, and skips other extensions without allocating any memory.
