[pstricks] Scaling pstricks output

[Peter Hutnick]

Hello,

I am using pstricks extensively for a math text.  I created several 
figures with pstrick and was happy with their "native" size.  For example:

\pspicture(-4,-4)(4,4)
    \psaxes{<->}(0,0)(-4,-4)(4,4)
    \psplot[arrows=<->]{-1.75}{1.75}{x 2 mul}
\endpspicture

But I have decided to move them into a two inch margin, so they need to 
be scaled down a bit.  Rather than bang them into shape by hand I 
thought I'd use the \scale macro.  That way I can change my mind again ;-)

So I added \pscustom{\scale{.5}}, which is too small, but it would be a 
start.  It didn't generate any errors, but it didn't have an effect 
either.  I tried wrapping the psaxes and psplot inside the pscustom{}, 
and that gave me errors.  I moved the pscustom to after the plot, to no 
avail.

Any advice?
