rotated `placeimage` broken

[Yuval]

Placing an svg after rotate often clips the svg or draws nothing, and sometimes messes up subsequent draws as well.
Some examples with this file:

s = readsvg("strip-tmp.svg")
@svg let
    rotate(-0.2)
    placeimage(s)
end 200 200

@svg for angle in 1.2:-0.2:-1.2
    @layer let
        rotate(angle)
        placeimage(s; centered=true)
        translate(50, 0)
        text(string(angle))
    end
end 800 800

It appears that the Rsvg.handle_render_cairo() call inside placesvg() modifies the coordinate system in such a way that, although it's enclosed in @layer ...end, changes can "leak" out into surrounding code and upset subsequent graphics.

You could try enclosing the placeimage() in another @layer ... end to see if that can really isolate the changes introduced by the Rsvg action...
