MGR bitmap

MGR bitmap is an image file format associated with the ManaGeR (or MGR) windowing system.

Format
"Old format" files have a 6-byte header, and "modern format" files have an 8-byte header.

Identifiers
The MGR software does not appear to use any filename extension for this format, but some third-party software uses .mgr.

Identification
Files begin with a two-byte ASCII signature:
