I rewrote Firefox's BMP decoder

I kind of hoped that this would be written in Rust. :)

BMP was one of the last formats that would be possible to &quot;decode manually&quot; (that is, read the actual data and paint the image from it). PCX was one of the other (using RLE)<p>Sure, easier to use a library, but sometimes you have some constraints

Interesting write-up. Still, why even support BMP?

How much of the mozillas code is written in C&#x2F;C++, and for what purpose...
