diff lib64gfx.h @ 510:43ea59887c69

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Start work on making C64 formats encoding possible by changing DMDecodeOps to DMEncDecOps and adding fields and op enums for custom encode functions, renaming, etc. Split generic op sanity checking into a separate function in preparation for its use in generic encoding function.
