Are the x11 100 and 75 dpi fonts absolutely necessary?
If Ubuntu has TrueType support, (as well as OpenType) why do I need all those bit-mapped fonts hanging around?
Can I delete them? (and/or generate ttf/ot versions for those I want to keep)
If I delete those fonts, will some ancient primitive packages still be looking for them and crash, or will I just get a substituted system default?
I've already read this topic: What fonts are absolutely required?
Answers were not really informative enough and kind of vague. I'm hoping my questions are more specific so I get a more definitive idea of just what the font system requires and does not.

All modern GTK+ applications use Xft for font rendering. Xorg bitmap fonts are installed by default just for the sake of backward compatibility. In other words you can safely uninstall them if you don't use any legacy applications (eg. gitk).
