%%%The first patch (BPy_scene_callback.patch) adds the callback stuff to the Scene type and also includes a 'FRAME_CHANGE' event that calls a python callable object on a frame change.

Demo of the frame change feature -> http://vimeo.com/14510810

The second patch (BPy_scene_rendercall.patch, applies on top of the first one) adds 'PRE_RENDER' and 'POST_RENDER' events and is mainly to demonstrate how easy it is to add new event types -- which turns out to be a three or four line patch (ignoring the change to bpy_rna_callback.c for having a default type).

Works in the same way as the current region.callback_add/remove() methods;

handle = C.scene.callback_add(print, ('hello, world',), 'FRAME_CHANGE')
C.scene.callback_remove(handle)

Yep, I know 'the plan' is to have the event system handle this but I figured since it was super simple to implement, may be useful to someone and works now I may as well share...%%%
