see_metal.tcl
Hides everything, then shows only li, m1, m2, m3 and m4.
foreach x $all { see no $x }
foreach x $metal { see $x }
The layer lists are the same as in see_all.tcl. Handy when tracing a route through a dense cell, where the implants and diffusion make it impossible to see which metal goes where.
see_all.tcl puts everything back.
