Added crop of BMP when scale occurs. I'll start making an encoder soon. But, to note - for the sake of all our sanity - MAKE YOUR TEXTURES A MULTIPLE OF 16 WIDTH, and a MULTIPLE of 8 height. God help you otherwise, because insertion and extraction isn't standardized with PSP tools. Some seem to reflow, some seem to insert padding. I'm incapable of figuring this out without some sort of flag.
