Clipping can interact in subtle and important ways with a variety of other map and layer level parameters, and became more error prone (but powerful) with the introduction of support for Proj4 in r330.
### Tickets related to bounding box clipping over time include:
https://github.com/mapnik/mapnik/issues/
* #127 - BBox clipping fails when there's no intersection
* #204 - map.buffer_size() does not seem to fetch data within buffer zone
* #308 - Mapnik bug when features with invalid coordinates for target projection are encountered
* #402 - Some points from PointDatasource get lost on reprojection
* #486 - Bounds clipping likely to fail if using map_buffer after r1348
* #506 - Add a Map level custom extent or max_extent to enhance clipping ability
* #548 - Layer query bbox not correct on Lambert Map
* #549 - Problem with local projections and worldwide data extent
* #751 - Better handling of bounding box transform (avoids need for 'maximum-extent').
