-/* This script os meant to convert a 256x256 pixel bitmap into an bitmap of
- * 8x8 pixel characters. When deciding upon the output format, i had the
- * video output of scanlines in mind. So there are 8 sections for each row
- * of pixels for a character cell, each secton containing the the pixel line
- * data of all 256 character codes. If you align this blob to 256-bytes, you
- * quickly fetch the data by pointing bx to the begin of the section for the
- * pixel line you are currently drawing, then set bl to the character value
- * you want to print and dereference [bx].
