MoveCmd,  RotateCmd,  ScaleCmd - coordinate transformation
       commands

SYNOPSIS

       #include <Unidraw/Commands/transforms.h>

DESCRIPTION

       The Unidraw library predefines three  purely  interpretive
       commands   for   performing   coordinate  transformations:
       MoveCmd defines a translation, RotateCmd defines  a  rota-
       tion, and ScaleCmd defines a two-dimensional scaling.

MOVECMD PUBLIC OPERATIONS

       MoveCmd(ControlInfo*, float dx = 0, float dy = 0)
       MoveCmd(Editor* = nil, float = 0, float = 0)
              Construct a new MoveCmd, specifying the translation
              distances in the horizontal (dx) and vertical  (dy)
              dimensions.

       void GetMovement(float&, float&)
              Return  the  translation distances specified in the
              constructor.

ROTATECMD PUBLIC OPERATIONS

       RotateCmd(ControlInfo*, float = 0)
       RotateCmd(Editor* = nil, float = 0)
              Construct a new RotateCmd, specifying the  rotation
              angle in degrees.

       float GetRotation()
              Return  the  rotation  angle  specified in the con-
              structor.

SCALECMD PUBLIC OPERATIONS

       ScaleCmd(
           ControlInfo*, float sx = 1, float sy = 1, Alignment =
              Center
       )

       ScaleCmd(Editor* = nil, float = 1, float = 1, Alignment =
              Center)
              Construct  a  new  ScaleCmd, specifying the scaling
              factors in the horizontal (sx)  and  vertical  (sy)
              dimensions  and  an  alignment suggesting the point
              about which the component should be scaled.

       void GetScaleing(float&, float&)
       Alignment GetAlignment()
              Return the scaling factors and alignment  specified
              in the constructor.
