Yes I agree with that, but J2D renderer really had the notion of geometries
grouped and divised by blocks. It was able to "Tile" a geometry or a set of
geometries in a way similar to what Java Advanced Imaging does for rasters. It
was able to know that a given "Tile" (meaning a rectangular geographic area) was
using coordinates at index 100 to 200 (for example) of a given set of
geometries.
I didn't talked much about that because that renderer was already considered
complex enough. The weak reference approach was proposed as a "less resistance"
path. In the mean time, trying to make its complexity level more acceptable is
one of the major challenge of that old renderer.
