If two pieces of code draw the same format differently, there is a bug
somewhere. That's like saying KDE and GNOME are allowed to render SVG,
HTML, PNG, or any other displayable format, differently, and it's OK.
But we all know that's not how things work, and it isn't true.

They need to be destroyed. Theme engines are one of the worst things we
have. It's very hard for artists to design a theme, when they don't know
how to code, if they have to write an engine.

I don't understand what you've said, and I've written a theme engine,
and worked on several others.
SVG is almost what we need for a common theme format. It's a bit off
from what we need, but it's quite close. What we need is something
similar to SVG, but where x/y/width/height/etc... are dynamic, and
specified at render time, so that we can have truly scalable art in
our themes, and we can eliminate the need for writing code to theme
If you really just want a cross-toolkit API for theme engines though,
perhaps you should take a look at the metatheme project. I think it
is/was hosted at http://metatheme.cx. I don't know what is up with it,
but that is exactly what the project was working on.
Of course, either of these solutions have the drawback of not being able
to make significant changes to existing widget behavior/look in the
theme, as you can now with the toolkit-specific engines, by manipulating
