If I could do round corners with normal <img> tags, I would,
but to the best of my knowledge this is impossible because all the
classic html tags are of type "display:block" which means they get ugly
spacing around them which will cause the round corner to misalign in
unpredictable ways across browsers. Really, I don't think I have much
choice. If I wanted to subclass Image to change this behavior, how
would I do it?

The fact that it is transient does not solve the problem I
mentioned. What I am saying is that if I render the exact same corner
multiple times (by hitting refresh on my browser 1000 times) then
render(Graphics2D) will get triggered 1000 times and I will have to
repaint it. What I am saying is that I know for a fact when the image
needs to be regenerated and when it should use the cached version and
RenderedDynamicImageResource does not give me the capability to do much
about it. The most I can do is g2d.drawImage(cachedImage) I guess but I
doubt it is as efficient as just giving it the BufferedImage
directly... I don't want to be cloning the image contents on every
rendering if I don't have to.
