      Issue #2303 - Please add Constant type of gradient interpolation ... · 68bf99e8
      Ell authored
      ... to make multi-color hard-edge gradient fills possible
      
      Add a new "step" gradient-segment blending function, which is 0
      before the midpoint, and 1 at, and after, the midpoint.  This
      creates a hard-edge transition between the two adjacent color stops
      at the midpoint.  Creating such a transition was already possible,
      but required duplicating the same color at the opposing ends of two
      adjacent stops, which is cumbersome.

      app: improve elimination of trivial blend-tool edit actions · 6036217d
      Ell authored
      ... from the undo stack
      
      When a blend-tool edit action modifies the gradient, do a deep
      comparison of the original gradient against the current gradient,
      to test if anything changed, instead of just assuming that
      something did change.

      app: port GimpData subclasses from ::duplicate() to ::copy() · 880d3bd1
      Ell authored
      Finish up commit 17583ff0, which
      ported GimpGradient from ::duplicate() to ::copy(), by doing the
      same for the rest of the GimpData subclasses that implement
      ::duplicate().
      
      We still keep GimpData's ::duplicate() virtual function around,
      even though it now points to the default implementation (which uses
      ::copy()) for all subclasses, since ::copy() is stronger than
      ::duplicate(), and we might want to have certain GimpData types
      that are duplicatable, but not copyable.

      app: improve curved gradient segment sampling · 1f3030eb
      Ell authored
      Improve the sampling performance of curved gradient segments, and
      its behavior when the segment's midpoint is close to one of its
      limits.

      app: improve num. stability of gimp_gradient_segment_range_compress() · 1b2a395e
      Ell authored
      When using gimp_gradient_segment_range_compress() to expand a 0-
      length segment, redistribute the range's endpoints and midpoints
      uniformly, rather than using the regular code path, which would
      result in NaN values.
      
      Make sure that the left and right endpoints of the range are
      *exactly* equal to the new left and right values.  Previously,
      they could be slightly off due to numerical errors.

      app: treat gradient segments as clopen ranges · 3aff0a1a
      Ell authored
      Treat gradient segment exents as [left, right) ranges, instead of
      [left, right], so that they don't overlap, and each point
      corresponds to a unique color.
      
      Perform less comparisons in gimp_gradient_get_segment_at_internal().

      ... which merges a segment range into a single segment, that spans
      the entire range, and has the same endpoint colors.  The merged
      segment's midpoint is at its center, and its blend function and
      coloring type are those of the range's segments if they're uniform,
      or the default ones otherwise.
