// This takes the font from AROS sources (under their APL license) and converts it to a format that can be used in microcontrollers.
// In AROS each line of each character is in a different block and the bytes are big endian.
// This code reassembles the font so that every line of the array is one character (each byte is a row of pixels), then reverses the endianess.
// Note that the font starts at ASCII char 32.
