Revision:
100:0b084475d5a9
Parent:
98:ecebed9b80b2
Child:
101:e0aad446094a
Corrected a defect where the portrait mode might be incorrectly inferred - then limits many commands to partial screen.; Remove set_font(). Use SelectUserFont() instead.; Removed unnecessary code in several places (redundant work).
