The width and height of the rounded rectangle must be all positive and
that's a bug. In the next release I'll normalize it so that it works
correctly even with negative values.

AWT images are not intrinsically bigger than PNG but in iText are always
converted to RGB, hence the size. There are also some simplifications
regarding transparency that can cause some unexpected side effects. If
you want the biggest size efficiency do all the manipulations and
clipping with jai, save the image to png and read it into iText with
Image.getInstance().
