Well, I think that when writing text, you translate the words in your head to list of textemes.
You write the string of textemes "backen" and Omega stores it in memory and it can do searches,
etc. When Omega send the text to the screen or the printer, it translate it to another string of
textemes, according to paper size, etc., and it becames "bak\nken", but this is only for creating
images, not for searching, nor speech synthesis, etc. It's like .tex and .dvi files. Texteme
strings can represent both kinds of text, graphical and non-graphical. Non-graphical texteme
strings have less properties than their graphical translation, but anyway they are texteme
strings. Also, there is not only 2 kinds of strings, of course, you can do multiple translations
and use only the properties you need (you can transform a regular string in a string without case
nor face information, etc.).
