This was part of my original design for the new theme systes, but was
removed because it was considered unneccesary complexity that only
affected phptemplate.
I think this is the right time to add it however, as it allows lots of
really creative things.
Also, most of the available template engines (smarty , phptal ,
phptemplate) are based on my original phptemplate code base, and as
such will benefit from this patch.

Attached is a patch that I would like to get into 4.6. I didn't realise
it but I am cutting this close.
What this patch does is give the ability to theme engines to be able to
handle all theme hooks with specifically having to code for them by
creating a function {theme engine}_{theme hook} (eg. phptemplate_pager)
What I have done to achieve this is I have created a new theme engine
hook called theme_handler. This will check to see if the current theme
has been set up to include this theme hook, and returns the function
that it should called to handle this theme hook. Most the time this
would most likely be a generic theme function.
This function is then called with exactly the same arguements as the
theme() was called with. (eg the theme hook as the first arguement) So
in the case of the pager the function is called like so

phptemplate_generic("pager", "", 10)

The method that I have used, theme engines are not required to use this
functionality, as some theme engines such as I think xtemplate will not
be able to handle this, but it works extremely well in phptemplate.
The reason that I have made this modification is that i can use a theme
engine such as phptemplate to create the theme, and if I want to theme
any additional features such as pager, menu_tree, I can without having
to modify the theme engine from standard. So this gives me the best of
both worlds.
So with the phptemplate engine all I need to do to make use of the
additional functionality is add template file to the themes directly
hook = hook.tpl.php, pager = pager.tpl.php, etc.
It also means in the case of the phptemplate engine the theme creaters
php skills can be limited, and still be able to expand the theme beyond
that of the engines capibilities.

It seems to me that this functionality belongs in PHPTemplate and not
another theme engine.
Are there any possible security issues raised with using such an
open-ended patch?
