    This functions is replaced by Function TextureEditor.
    Select surface with right mousebutton - select "Texture".

    Textures

     For textures can JPG and BMP files can be used.

     Textures can be used for 2D-tags
     Textures can be applied to Surfaces

    2D textures for tags:
      A picture is display always normal to the viewer.
      Interactive activation: CAD / N-Image

    Textures for Surfaces:
     Interactive activation: Modify / Surface Texture.
     Textures can be applied to the following types of Surfaces:
      - Planar surfaces
      - Meshes.
       The texture can be scaled, moved and rotated activation(modifiy).
       Scale and offset for x and y separately defined.
      Imagecorrection eg with Gimp:
      - remove distortion: Tools/transformation/perspectiv
      - crop image: Tools/transformation/crop
      - scale image: Image/Image scale
        For normal quality scale one meter to 100 pixels

    Load texture from File
     Load and activate a texture from a file:
     Select a JPG or BMP file;
     the texture name is now displayed as active texture.

    activate Texture from Surf
      Activate a already used texture :
      Select a textured surface.
        (unhilite texture (in mode VWR only): right mousebutton)
      Texture and Surface will be activated.
        You can now modifiy the texture -
        or apply it another surface.

    apply active Texture
     Applies the active texture on a surface.
     Select a surface.

    Remove Texture
      Removes the texture of a surface.
      Select a textured surface.

    fit Size
      On:  scales the image to the size of the surface
      Off: the image is applied with its original size

    Reload
      Reloads the image of the active texture.
      (if eg. an image already loaded has been modified ..)

    Scale - Offest - RotAng / Modify Texture:

     - Scale X / Y (Scale texture; cursor keys)
     - Offset X / Y (moving texture; cursor keys)
     - RotAng (torsion in degrees; Cursor-left/right)

      Modify the values with the keyboard: update with the return button.
      Modify the values with the cursor keys: updated dynamically.
      Next entry with the Tab key.

    Analyze dimensions from a photo:

    Using a photo size should be analyzed:
      Equalize the photo.
      Create a surface from a rectangle (in Z=0) with the size of the photo;
      If the photo displays a area of 3 x 5 meters:
          S20=REC P(0 0 0) D(5 0 0) D(0 3 0)
          A20=S20
      Apply the texture.
      Set points  (Select / PT -- Position)
      Measure between points (Analyze Dist).

    Open / ToDo:
     Export of textures with VRML ..
     Support of 16-bit-display
     Transparent textures ..
     Billboards ..
