    map-{absolute,relative}: factor out common code; add scale matrix · 7e1ddbb2

    Factor out the common code of gegl:map-absolute and
    gegl:map-relative to map-common.h, and include it in both
    operations.
    
    When using a non-nearest sampler, use the gradient of the input
    field to construct a scale matrix to pass to the sampler, to reduce
    aliasing when the input is downscaled.
