Details:

Currently there is no support for BMP in NSBitmapImageRep. This propagates
further, so that NSImage cannot load BMPs either.

Looking at how NSBitmapImageRep is implemented, this seems easy enough,
practically a starter project.

For instance, I wanted to display /sys/firmware/acpi/bgrt/image which is
populated by the ACPI BGRT Linux kernel module on many modern UEFI machines.
This comes from an ACPI table used by operating systems such as Windows to
display an image during boot that matches what is displayed on the POST
screen.
