Copperbox revision 885.

More work on SVG output particularly text labels, currently multiple lines are printed in the wrong vertical order. It looks like another difference between SVG and PostScript - coordinate (0,0) is bottom left in PostScript, from a cursor reading it looks like it is top left in SVG.

These arbitrary differences are really rather disappointing - should I simply transform the coordinate frame [1 0 0 -1] before creating the picture? It's easy for me to do, but potentially confusing for anyone deciphering their output if they're expecting normal SVG.

-- Update - the [1 0 0 -1] transformation won't work of course, as text (well, the Beziers and lines that make text) will be translated along with the location point, thus the characters will be printed upside down.
