Part of the reason for this is that other languages and UI widgets
have fairly limited capabilities, as far as appearance. With REBOL,
you can use the graphics pipeline, draw commands, set custom edges
(which, themselves, are completely customizable), embed images, and
more. The problem is that there are so many ways to do things, that
you don't know how a particular style does it without analyzing the
source. Another "problem" is that the whole UI system is very dense,
in code terms, so there's a lot of neat stuff going on that minimizes
the code, but makes it harder to understand.
I think the entire VID system, at the mezzanine level, is around
4K LOC.
