rev 133, os-x 10.4, java 1.4

the default setting (JAVA2D renderer) for lines is noSmooth() but for scaled images (image
(img,x,y,w,h) calls) it seems to default to smooth().

not sure what to do for this one, because it's rare that people actually
want images to use nearest neighbor interpolation, even if the rest of
their sketch uses noSmooth().

however, maybe that's what we have to do to be strict, and will use hint()
to alter the behavior.

fixed for 0149, now noSmooth() is called by default, so that the rendering
hint is set for Java2D.
