-  Convert the input RGBRGBRGB pixel buffer to the BMP pixel buffer format. There are 3 differences with the input buffer:
-  -BMP stores the rows inversed, from bottom to top
-  -BMP stores the color channels in BGR instead of RGB order
-  -BMP requires each row to have a multiple of 4 bytes, so sometimes padding bytes are added between rows
