In the ShapeFeature, convert x.shape[1] to Shape_i. This will help compare shapes.
Add ShapeFeature.same_shape, that try to compare 2 var shapes.
Add local_useless_inc_subtensor.

Remove the IncSubtensor when we can infer all the shapes are the same.
Make opt local_useless_subtensor convert to subsample when we reverse.
Disable opt in some case discovered in new tests crash with the new opt.
Better auto function name if we call var.eval().
small doc update on Theano vision.
skip some tests when scipy isn't available.
Add comment
Remove old deprecated stuff.
Disable code optimization warning that I think shouldn't be done.
