John the CDraw code is proprietary and has been the reason many Linux developers have not wanted to contribute.

The linux developers wanted access to the CDraw code which Xara Group Ltd. is understandably unwilling to release as open source. That would be like willingly putting themselves out of business.

Although the open source Cairo could be used to continue the Linux development by 3rd party coders. No one seems to want to use code that is not up to CDraw's abilities.
