[Gvsig_english] JumpBrigde Buffer processing

[Fran Peñarrubia]

Touché! :-)

I have 7-zip installed in my computer, but may be it's and old version. I
couldn't open it.

Anyway, now I've read your code.

I think you can try 2 things to speed up your driver.

1.- Don't convert JTS Geometry. Wrap it ... like Geootols does. In fact,
you can use FLiteShape:
      public IGeometry getShape(int index) throws IOException {
               Feature feat = featDataSet.getFeature(index);
               FLiteShape shpLite = new FLiteShape(feat.getGeometry());
               IGeometry gAux = ShapeFactory.createGeometry(shpLite);

               return gAux; //FConverter.jts_to_igeometry(feat.getGeometry());
       }

2.- Use the same renderer as shape files. (Faster). The only thing you
need is to implement the interfaz BoundedShapes
(com.iver.cit.gvsig.fmap.drivers.BoundedShapes).
And to avoid recalculating each time the extent of every shape, you can
store the shape bounds into an ArrayList or something like that.

I didn't tryed it, but with this two modifications, it should go faster.

Have fun.

PS: FLiteShape it's very similar to LiteShape from Geotools. It's one way
to explore a future bridge to geootols (if needed ;-) ) .
