Change what layers are displayed in the window
<HR>
<H3>Shortcuts:</H3>
<BLOCKQUOTE>
Mouse buttons 1 and 3 pressed in the GUI window toolbar implement the
<B>see</B> and <B>see no</B> commands for the layer represented by
the toolbar button.
</BLOCKQUOTE>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>see</B> [<B>no</B>] <I>layers</I>|<B>allSame</B> <BR><BR>
<BLOCKQUOTE>
where <I>layers</I> is a comma-separated list of layers
in the technology, and may also be the character <B>*</B>
indicating all layers but not labels, <B>$</B> indicating
all layers including labels, <B>labels</B> indicating
only labels, <B>error</B> indicating DRC error paint,
and <B>subcell</B> indicating subcells.
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>see</B> command allows various layers in the layout
to be made visible, including labels and error paint.
With the keyword <B>no</B>, the command causes these layers
to be made invisible on the display. <P>
The keyword <B>allSame</B> is a special use and indicates that
non-edit cells should be drawn in the same manner as the edit
cell, rather than being drawn in the "pale" styles. <P>
Undisplayed layers generally do not respond to commands such
as <B>erase</B> or <B>select</B>. However, network selection
will select across invisible layers, and copying or moving
such a network selection will alter the invisible layers as
well as the visible.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>see</B> is implemented as a built-in command in <B>magic</B>.
</BLOCKQUOTE>
<H3>Bugs:</H3>
<BLOCKQUOTE>
It should be enforced everywhere in the code that invisible
layers cannot be altered. This may require removing invisible
layers from a selection after doing a network connectivity
search.
