// This macro draws 4 Latex-style formula in a canvas and prints the canvas
// as a Postscript file.
// Note that this macro relies on a first implementation of the TLatex class.
// There are still some discrepancies between the result on the screen
// and the result on Postscript.
// Also some differences will be seen between Unix servers depending
// the version of X in use. Results on WindowsNT are also slightly different.
