Yes, I know, it was discussed on this list two or three months ago. 
Their implementation covers basic 2d functionality, but none of really 
complicated stuff is implemented (raster-based functionality, meaning 
composites, paints, etc). I have done some experiments on implementing 
opengl java2d myself, but it seems that full software path has to be 
implemented anyway for most complicated cases. Which leaves opengl only 
for acceleration (and not as I have hoped, for simplifying part of 
implementation).

Question is if classpath will have any benefits from having 70% complete 
accelerated java2d implementation, at the same time requiring additional 
100% work to get rest of stuff implemented (not just 30%, as base stuff 
would need to be reimplemented to pure-software path), plus code being a 
lot more complicated due to need for fallbacks from acceleration 
everywhere ?
