PROGRAM 2: Behavior of scaling

CHARACTERISTICS: nnnn

OPERATOR SCRIPT: passive test.

DESIGN:

TEST: #SR 1 2 5
      "<Scale 3> should return a correct representation for the
       transformation to scale a 3D point, with non-zero parameters."

Set scale parameters (fx,fy,fz) to (-33.3, 0.0076, 2.2)
<Scale 3> with fx,fy,fz returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 5
      "<Scale 3> should return a correct representation for the
       transformation to scale a 3D point, with zero parameters."

Set scale parameters (fx,fy,fz) to (0.0, 0.0076, 0.0)
<Scale 3> with fx,fy,fz returns act4x4 = actual array
Compute exp4x4 = expected array
pass/fail depending on (act4x4 represents same transformation as exp4x4)

TEST: #SR 1 2 6
      "<Scale> should return a correct representation for the
       transformation to scale a 2D point, with non-zero parameters."

Set scale parameters (fx,fy) to (-33.3, 0.0076)
<Scale> with fx,fy returns act3x3 = actual array
Compute exp3x3 = expected array
pass/fail depending on (act3x3 represents same transformation as exp3x3)

TEST: #SR 1 2 6
      "<Scale> should return a correct representation for the
       transformation to scale a 2D point, with zero parameters."

Set scale parameters (fx,fy) to (0.0, 0.0)
