RAW BITMAP FONT FORMAT SPECIFICATION

Structure:
- 256 glyphs (0-255)                   Example ('A' @ 0x410):
- 8 wide x 16 tall                     00011000  (row 0)
- Each row: 1 byte (8 bits)            00100100  (row 1)
- MSB = leftmost pixel                 01000010  (row 2)
- 256 glyphs x 16 rows = 4096 bytes    01111110  (row 3)
                                       ...

Layout:                                Bit Encoding:
  Byte 0-15:   Glyph 0x00              1 = pixel on
  Byte 16-31:  Glyph 0x01              0 = pixel off
  ...                                  Bits: 76543210 (7 = left)
  Byte 4080-4095: Glyph 0xFF
