[mapserver-dev] plugin renderer support status update

[Stephen Woodbridge]

Thomas,

WOW!, this is a very cool Christmas present indeed! For "pre-alpha" code 
the results are already very impressive, especially at only 500 LOC for 
the Cairo plugin. Thank you very much.

Is the plan for the OpenGL effort to build on this work also?

A Very Merry Christmas to you and everyone on the list.
