hi,
I wanted to let people know about the status of my native java2d work.
this is visual work and a picture tells at least 1024 words:

hi,
I recently posted some new files to the java-patches list of the gcj
project, containing the beginnings of my cairo java2d

hi,
I would like to attach some extra methods to a singleton object of
some sort -- something like Toolkit or GraphicsEnvironment, or a
classpath-specific subclass of these -- to produce peer or peer-like

Hi,
java.awt.image.BufferedImage has a small bug, where it assumes that
its sample model is a ComponentSampleModel when copying blocks of
pixels. This is not always true. The attached patch fixes this
problem.
