People are used to thinking about the aspect ratio of displays and used to not thinking at all about that of pixels. Most of the modes are simplt 4:3 modes and the text area is the entire window. The only oddball here is the Commodore 64 and 128 40-column modes. Because they have a border around them that's wider on the sides than the top/bottom, the display aspect ratio is actually narrower than a normal NTSC screen (6:5). It seems the PAL version actually has square pixels, but nobody has asked for a PAL Commodore mode, and I think that has a different colour palette too so I'm not doing it. Just to frustrate DigitalMan a bit, the default custom aspect ratio is now 4:3 (but can be configured). At present, modifying the custom mode while *in* the custom modes "works", which no sane person would want when adjusting the aspect ratio.
