I looked at this... but I know its functioning for some people...

conditional loading interface. cleaned up cruft. Probably thoroughly broken. :)

added transformer_macro_queue function.

something else in the modules. 5.0 conversion to begin later today.

(extensions, mimes, and priority) for a macro.

adding transformer_transform_info which returns transform info from a
transform plugin.

them, but the admin interface is all that is working right now.

I think its a major improvement.
@todo validation.

macro list/add/delete works... need to split add into its own callback.
macro edit screen is in place with links to add new transforms with the menu item
for the transform/add.

next steps: transform add interface, transform delete interface, macro/transform edit interface.

renaming all crud functions, making more formapi / drupal 5 ready, sketched in a js editor
callback and documented some session structures for managing history, layers, and selections.

Its basically stripping the UI out of imagecache, splitting the image actions
into their own includes, changing the diction from preset/action to
transformation/transform, adding the db for the queue. added a callback for
javascript calls into the transform engine, extended actions to define mimetypes and
extensions they can operate on.
