There are many elements that we could do interesting things with, that we
currently don't. linkscript, style could all be pressed into service to provide
dynamic loading of extra content. The ability to create a kind of import
statement for Javascript is particularly interesting.

It would be good to be able to to custom rollovers by manipulating the img,
object or param elements. Maybe code that altered image sizes would also be
cool, so this probably deserves a section of its own.

We could do more with the a element than we do. We could have setValue() for a
hyperlink set the destination rather than the link text although this might get
confusing, maybe a new function is required.

We could alter:
- img
- object (?)
- a
