Feature request: make deeptile files with exrmaketiled

[fnordware]

exrmaketiled does not work with deep data right now. Let's fix that.

Looking into the OpenEXR issue backlog. Is this an issue, or safe to close?

[fnordware]

Well, it's a feature request. The exrmaketiled utility can turn a scanline EXR into a tiled EXR. Might be nice if it could do the same for deep.

Do you have a use case?
Making a one level tiled deep image would be trivial, but the OpenEXR library doesn't support filtering of deep pixels to produce mipmap/ripmap images. Robust deep filtering is a hard problem.

Unless there's a compelling demand for converting scanline deep images to one level tiled deep images, it may be better not to support deep scanline images at all in exrmaketiled until it has feature parity with regular scanline image inputs.

[fnordware]

Well, that's a good point.

I guess if someone wants it badly enough they can implement it themselves.
