This ensures that fillvalue::Colorant is of the dominant role of eltype of PaddedView.

One consequence of this is transparent color is correctly filled even if img isn't of eltype ARGB:

PaddedView(ARGB(0, 0, 0, 0), img, indices)

This PR also reexports PaddedViews to introduce PaddedView and sym_paddedviews(JuliaArrays/PaddedViews.jl#23)

Ref: This is a rework of JuliaArrays/PaddedViews.jl#25 and co-operates JuliaArrays/PaddedViews.jl#26

This exports two new names: PaddedView and sym_paddedviews
This ensure that `fillvalue` is of dominant role of eltype of PaddedView.

One consequence of this is transparent color is correctly filled even if
`img` isn't of eltype `ARGB`:

`PaddedView(ARGB(0, 0, 0, 0), img, indices)`

This is a rework of JuliaArrays/PaddedViews.jl#25
and co-operates JuliaArrays/PaddedViews.jl#26

These two PRs (this and #127) for the imshow alternative are sleeping for many days. My personal usage experiences on this are pretty positive so I'm planning to merge it in days despite the lack of review.
