 When displaying vector data in a shape file using on the fly projection
 some data is not being displayed.  I suspect that this is due to
 incorrectly determining a bounding box for the data in the source data
 coordinate system when the data is being selected for display.

 To replicate:
 Open a QGIS session.  Attach the two attached shape files (testpoints,
 coastll) - grid of points and coastline.  Change the project properties to
 on the fly projection and the projection to EPSG:2193 (New Zealand
 Transverse Mercator).  Zoom to the extents of extents of the coastll
 layer.  Note the position of the southernmost points of the testpoint
 layer in relation to the coastline.  Pan the view upwards.  Additional
 rows of testpoints are displayed at the southern edge of the grid which
 had been incorrectly clipped in the previous view.  (see attached images
