Why is scale=(-1,1) relevant for the text? Does xcircuit have an x-axis from right to left? For postscript this is not the case, it is from left to right, bottom to top. A simillar problem appears with graphical representations of functions, data sets, statistical material etc A program like grace caring about such data has a similar problem for SVG output, because the y-axis of SVG points down (top to bottom). I think, they use a scale(1,-1) and some translations for the complete set of graphical objects and use additionally a matrix transformation on each text element (which can be decomposed again in a scale(1,-1) and some other transformations of course).
