The idea came from an embedded browser development project. Benjamin
I want to porting WebKit to a new platform, the platform can only
provide video address programming interface. So I need to porting
DirectFB, Cairo, GTK and so on. However the hardware resources are
limited, can't running so much software, I need to find a more
lightweight and high quality solutions, so I develop the picasso
library. The same code base can run on different graphics system does
not depend on the features of graphic system, this is the goal of
Picasso.
To experiment with this, you could create your own git branch and try
implementing a GraphicsContextPicasso (see
Source/WebCore/platform/graphics/cairo | skia) - similar to
GraphicsContextSkia and GraphicsContextCairo. Then you need to typedef
the WebKit GraphicsContext to the Picasso graphics context and
instruct your browser app to do all WebKit rendering into the Picasso
GraphicsContext.
Gettings simple web pages to render with a new backend, somewhat close
to the other backends might not even take that long. However, getting
every detail right, like layers with opacity, rounded corners, correct
clipping, full SVG support etc. is a rahter large amount of work.
