[vtkusers] Imagedata/Uniformgrid non axis aligned

I started writing some code for a particular job yesterday and then
realized that I can't do what I want to because it is not possible to
have a non-axis aligned vtkImageData - or better vtkUniformGrid.
I wonder if there is a solution to having an image-like structure that
is non axis aligned using some AMR box or heirarchical box dataset
instead. I had a quick look at the classes, but didn't see an immediate
solution. I need the dataset to be efficient like vtkImageData, but
arbitrarily orientated. I need to add a transform to a vtkImageData at
the dataset level, applying a transform to an actor would not help. The
data needs to be really transformed in space (for resampling purposes).
Can anyone suggest an alternative?
If not, is there any other demand for modifying vtkUniformGrid perhaps
to take a transform so that functions like findcell/getpoint/bounds etc
are routed through it? (also, would it be realistic to add this to
uniform grid, or are there too many places where assumptions are made
about voxel corners etc).
