• with-bounding-rectangle* used to have optional max-x and max-y arguments. They are
  now required.
  
  
• The function bounding-rectangle-set-edges has been removed, since bounding rectan-
  gles have been made immutable. There is no replacement for it.
  
  
• bounding-rectangle-position* has been renamed to bounding-rectangle-position,
  since the term "position" unambiguously refers to an (x;y) coordinate pair. A compatibility
  function will be provided.
  
  
• The functions bounding-rectangle-left, bounding-rectangle-top, bounding-rectangle-
  right, and bounding-rectangle-bottom have been replaced by bounding-rectangle-
  min-x, bounding-rectangle-min-y, bounding-rectangle-max-x, and bounding-rectangle-
  max-y. This is because left, top, right, and bottom are ill-specified. Compatibility functions
  will be provided.

Affine Transformations

• The function make-3-point-transformation has had its argument list changed from
  (point-1 point-1-image point-2 point-2-image point-3 point-3-image) to (point-1 point-2
  point-3 point-1-image point-2-image point-3-image). This was done because the original
  argument list did not group together inputs and output, which was confusing.
  
  
• The function make-3-point-transformation* has had its argument list changed from (x1
  y1 x1-image y1-image x2 y2 x2-image y2-image x3 y3 x3-image y3-image) to (x1 y1 x2 y2
  x3 y3 x1-image y1-image x2-image y2-image x3-image y3-image). This was done because
  the original argument list did not group together inputs and output, which was confusing.
  
  
• compose-scaling-transformation, compose-translation-transformation, and compose-
  rotation-transformation have been replaced by the six functions compose-translation-
  with-transformation, compose-scaling-with-transformation, compose-rotation-with-
  transformation, compose-transformation-with-translation, compose-transformation-
  with-scaling, and compose-transformation-with-rotation. This was done because
  the six functions implement all of the optimized useful cases of composition of transforma-
  tions, and new names are required for all six. Compatibility functions will be provided for
  the three CLIM 1.0 functions.
  
  
• transform-point* and untransform-point* have been renamed to transform-position
  and untransform-position. Compatibility functions will be provided.
