Decodes BMP files of 1, 4, 8 (palette, optionally RLE), 16, 24 and 32 bits per pixel, with channel masks for 16 and 32. Palettised and 24-bit images become RGB8. 16 and 32-bit images become RGBA8 when they have an alpha mask (or, for 32-bit without masks, any nonzero alpha byte) and RGB8 otherwise.
