+
+""" Key Points:
+BDF fonts are bitmap fonts, so they have a fixed size
+The bitmap data is stored in a packed format (8 pixels per byte)
+Each bit in a byte represents whether a pixel should be drawn (1) or not (0)
+The pitch value tells you how many bytes are in each row
+The advance value tells you how far to move for the next character
