* Cleaned up fugly logo by Albert Lai <aylai@unixg.ubc.ca>
|
|
* Width is now 70 chars to be exact 4 pixels/char for 280 HGR resolution
|
|
* Bit-packed Logo takes up 210 bytes (2 bits/char) compared to 80*12 = 960 byte

|
* X is now symmetrical
|
|
* Fixed L,i,n kerning
|
|
* Fixed x Penguin kerning
|
|
* Fixed L to fit
|
|
* Chopped off 2 columns of penguin to fit 70 chars
