    Partially revert "buffer: fix source rect passed to gegl_resample_{linear,boxfilter}()"
    
    Commit a7c730cf6e841a46d3b4546b86a234ae59206e9c trimmed the sample-
    buffer padding from the source-rect passed to the resampling
    functions.  This isn't strictly necessary, and has the negative
    effect of preventing the same padding from being present in the
    converted sample-buffer when using any of the _generic() resampling
    functions, causing artifacts.
    
    Revert the trimming of the resampling source-rect, though keep
    avoiding reading padding-region data from the source buffer, which
    should still be unnecessary.
