[AccessD] Good Interface Examples

I believe all raster screens use RGB additive colours, however vector 
graphic screens(draws only a single line at a time) like the old 
Tektronix colour graphics terminals, used subtractive CYM colours. This 
only got messy when you were trying to add 35 mm cameras to capture the 
screen output to slides. I used this back in 80's for IBM main frame 
3270 colour terminals. The 35 mm terminal adapter was expensive at the 
time around $5000.
