Function: make_transform ([<var1>, <var2>, <var3>], <fx>, <fy>, <fz>) Returns a function suitable to be used in the option
transform_xy of plot3d. The three variables <var1>, <var2>, <var3> are three dummy variable names, which represent the 3 variables given by the plot3d command (first the two independent variables and then the function that depends on those two variables). The three functions <fx>, <fy>, <fz> must depend only on those 3 variables, and will give the corresponding x, y and z coordinates that should be plotted. There are two transformations defined by default:
spherical_to_xyz; see the documentation for those two transformations.
