Now every function node except for "Sample UV Surface" supports
both list and grid outputs. Any grid or list input means the output also
has that type (combinations of grids and lists aren't supported).
However note that some nodes also have inputs that are always fields
evaluated on the target geometry.
There is still plenty of room for optimization. For grids and lists, all
the outputs will be computed, and every function node is evaluated
completely separately. It would be better to build a network similar to
fields and evaluate it lazily (when topology doesn't change anyway).
