tkrgl: tkrgl functions
In rgl: 3D Visualization Using OpenGL

Functions from the former tkrgl package.

The tkrgl package contained functions to use TCL/TK to control an rgl scene on screen. These functions have now been merged into rgl, with a goal of dropping the tkrgl package.

To avoid conflicts with rgl names and to indicate the TCL/TK nature of these functions, they have all been prefixed with tk:

tkpar3dsave: Formerly tkrgl::par3dsave, allows interactive saving of scene parameters.
tkspin3d, tkspinControl: Formerly tkrgl::spin3d and tkrgl::spinControl, create buttons to spin the scene.
