// Camelot expects) is use a postcript page transformation matrix to invert the
// page, and for the postscript to be written in native DPI coordinates with the
// origin at the TOP left of the page. What wxWidgets does is write its postscript
// in the more natural way with the origin at the BOTTOM of the page, and handle
// the coordinate inversion wihin wxWidgets.
//
// Note that this means while our internally generated PS expects a transformation
// matrix that flips the Y coordinate (as the windows drivers produce). We
// can't change the transformation matrix in the prologue because this would
// affect wxWidgets output (and also it's technically difficult to do). We can't
// change our own rendering matrix (so we produce the right coordinates) because
// lots of things seem to explode with a matrix which flips the Y access (negative
// scale factors etc.). We can't just change the coordinates we write because
// other things (e.g. bitmaps) use the native render matrix. So what we do is
// temporarily invert the PS transformation matrix during the period of our output.
// This seems arcane but reasonably extensive research suggests it is the best
// way forward. It's restored before we do any OS output.
