Neat, do you have a project homepage for your scenegraph?
All JogAmp JOGL API follow Mathematics and is using Cartesian coordinate systems.
We think 2D designs should use Cartesian coordinate systems as well hence no need to have a special 2D version of the API with a what we think is crazy "inverted TV scan-line" coordinate system.
Programmer friendly 2D API's should use:
• 2D regular Cartesian grid
• Origin (0, 0) at the lower left (OpenGL convention)
• Pixels are defined at intersections
If you read the paper
sampleCount is used for this additional rendering pass to produce the VBAA technique.
jogl-fonts-p0.jar is part of jogl test package containing the junit tests
unfortunately I do not know what maven dependency and artiactId you need to add to have the test packages added. I hope someone with more maven expertise can help you locate the right depencency and artifactId to include this jar containing the fonts. At least it is correct that it is not intended to be included the the jogl-all-main since jogl-fonts-p0.jar is part of the junit tests.
