No idea, I don't even know what they are. The application I'm trying to get working is a little open source project I've been involved with for the last few years (pythianproject.org), written in Delphi. The OpenGL initialization code was produced by the Delphi JEDI organisation which probably means it's been reused a fair few times in various Delphi OpenGL projects.
Can you give me the actual parameters used by the application ? Because if it only ever uses plane '0', Wine can implement it pretty quickly by just calling the standard CreateContext function.
