3.4.6:
- svgdraw and psprint: draw text after images as done in screen draw. Correct postscript / pdf
image zoom factor to match scaling with other xschem elements.
- do not reset xctx->netlist_name after doing `Netlist` from gui (xschem netlist -erc)
- process tcleval(....) (if present) in symbol `name` argument
- let symbol name entry box in component edit property dialog box expand in X direction
