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

| "yz" | modern format, 8-bit aligned |
| "yx" | modern format, squeezed |
| "xz" | old format, 1-bit, 32-bit aligned |
| "zz" | old format, 1-bit, 16-bit aligned |
| "zy" | old format, 8-bit, 16-bit aligned |
| "xy" | same as "zy"? |
