[gl4java-usergroup] Found a bug in the tesselator patch

[Pepijn V. E. <pep...@lu...>]

I found a small bug in my tesselator patch :) Before adding a
callbackentry, SetCurrentCallbackObject wasn't called. Because of this
findCallbackNode could sometimes not find the matching callbacknode (in
the case where a callback had already been defined for a given
tesselator). A new callbacknode was then added to the callback list.
When the callback was actually used, the FindCallbackEntry method would
find the first node in the list, being the old callback node.
What I've done is duplicated some of the callback methods so there is a
version that takes the current callback object into account, and one
that ignores it. That way the tesselators work fine now and the nurbs
and quadrics stuff remains unchanged.
Eventually, I guess the nurbs and quadrics methods should call
SetCurrentCallbackObject too, which removes the necessity of the
duplicated code. If I want to implement this should this also be put in
the manual part or can C2J be modified to handle this?
