Bug: unitsize() does not work to set unitsize of other pictures about asymptote

[johncbowman]

You forgot to fit picture p to a fixed sized frame before adding it to currentpicture (that will freeze it's scaling, instead of using the scaling of currentpicture). Here's a minimal example:

unitsize(1cm);
draw(scale(3)*unitcircle,red); // radius 3cm. for reference

picture p;
unitsize(p,5cm);

draw(p,unitcircle);
add(p.fit());

In retrospect this looks like the same issue as #450 .

No, that was a separate issue; see my explanation above.
