If I call "rsvg -w 30 -h 0 foo.svg foo.png", rsvg gives a cryptic=20
warning and a random bogus output PNG.  It should give a useful error=20
message and (I think) no output PNG.

(process:26064): librsvg-WARNING **: rsvg_start_svg: width and height=20
not specified in the SVG, nor supplied by the size callback

The same is true if a negative value is given.


An easy fix would be to test for width or height <=3D0 instead of testing=
 for =3D=3D
-1, but I don't know if that's the best solution.
