27106	Document which template filters can be used in Python code (and how)	Baptiste Mispelon	Ryan Cheley	"The Django template language ships with a lot of filters. Usually they're implemented as Python functions and can be imported and used in your own code.

However this particular usage is not documented (take the example of the various `truncate*` filters [1]).

I think it would be useful to know:

1) Which template filters can be used as functions;
2) Where to import them from and how to use them;
3) If there are limitations/gotchas related to using them.
