    app: add GimpGenericTransformTool · 4c71ee8e
    Ell authored
    A subclass of GimpTransformTool, to be used as a base class for
    transform tools that calculate their matrix based on 4 pairs of
    input/output points, and that display the transform matrix as their
    GUI (this includes the unified, perspective, and handle transform
    tools; the next commit ports them over to
    GimpGenericTransformTool).
    
    When the resulting matrix of the input/output mapping sends any of
    the output points to, or past, infinity, GimpGenericTransformTool
    sets GimpTransformTool::transform_valid to FALSE, and displays an
    appropriate message in the tool GUI, instead of showing the matrix.
