Provide a generic "slide/glide" tile
------------------------------------

                 Key: SQ-1021
                 URL: http://tracker.squeakland.org/browse/SQ-1021
             Project: squeakland
          Issue Type: Improvement
          Components: etoys
            Reporter: Stephen Thomas
             Fix For: future release


So I am thinking of something similar to Scratch's <glide [n} secs to x:[ ] y: [ ]> tile, but more generic.

So perhaps a tile that changed any numeric value incrementally over a period of time. Something like: <glide:  <numeric Attribute> to: [new value] in [] secs.

Use Cases:
   Change the width/length of a playfield, to create a Mouse Over drop down type menu
   Glide to position X,Y in z seconds
   Changing alpha to create fade in/fade out effects
   Changing other color values (just for fun)

I tried doing this in the existing Etoys and it is possible, the problems (at least for me) are:
  1) you have to re-create the same basic script each time for each attribute and player
  2) You can't pass an attribute in as a parameter to a script (this I think would solve the problem, if I could pass more than one variable to a script, I could pass the player the attribute, the time and the new value.
