"Change Set:		ColorSeesTurtleTrailsToo2-nk
Date:			7 July 2003
Author:			Ned Konz

This is a clean version of the ColorSeesTurtleTrailsToo-nk change set,
intended to be used if you didn't load a prior version.
	
If you haven't loaded a prior version of this change set, please load
ColorSeesTurtleTrailsToo-nk instead of this one.

The preamble will check for this.

This change set does the following:

* Makes turtle trails appear above the background sketch if any
* Makes #color:sees: and #touchesColor: tests work right with display
depths > 8.
* Makes #color:sees: and #touchesColor: work right in the World
* Makes the grid visible to #color:sees:, #colorUnder and #touchesColor:

It may break some scripts that use #color:sees: or #touchesColor: on
playfields that have background grids, if the color being sought is
exactly the same color as the color of the grid. To fix these scripts,
change the grid color slightly.

It also will use more memory for the turtle trails form when your
display depth is > 8. However, this memory will be discarded before
saving the image.

This change set also removes an unnecessary ColorPatchCanvas copy that
was in #patchAt:without:andNothingAbove:
