Warp9 Font *.FNT<br />
<br />
The font format defines characters 0-255.<br />
Each character is stored as 16 bytes, one byte for each row in the character. <br />
Characters are rendered as 8x16 pixels, thus 16 * 256 = 4096 bytes.<br />
<br />
4096 bytes character data<br />
1 word half height flag [0 = not allowed, 1 = allowed]<br />
