Galena: a free implementation of the Java2d graphics system in C++

Galena is an effort to implement most of the functionality of the Java2d graphics subsystem in C++. Why? Because we don't have a good library for C++ to match Java2d. C++2D can also be used in python, perl, or gcj.

Galena aims for

• Offscreen buffering
• multiple rendering backends.
• antialiased rendering as a capability provided optionally by the backend renderer. Antialiasing can be turned on and off as needed.
• Arbitrary clipping
• Bezier shapes, proper stroking
• NURBs
• polygons -- arbitrary, self intersecting. holes?
• lines -- arbitrary width, style, capping, mitering.
• nurbs and beziers for curves (presuming beziers are faster).

The initial system might be built on the tarpaulin system. Tarpaulin has:

• Offscreen buffering
• antialiased rendering only.
• Arbitrary clipping
• Bezier shapes
• polygons -- arbitrary, self intersecting. holes
• Loading images through gdk-pixbuf
• Freetype based character painting. No support for using glyph shapes directly

Todo

1. Pull out medieval from tarpaulin and fix resizing of window.
2. Implement lines/stroke.
