gdalwarp over-fails when some areas are not transformable

Description

GDALWarpOperation::CollectChunkList() will stop collecting chunks to transform when one subregion fails to transform using ComputeSourceWindow(). In practice this means big images that need to be split up a lot and that have invalid regions will fail to transform quite a bit of the image.

Milestone: 1.9.2
Resolution: fixed
Status: newclosed

corrected in trunk (r24878) and 1.9 branch (r24879).

This problem likely has existed for a long time.

It will be accompanied by one or more errors like:

ERROR 1: Too many points (441 out of 441) failed to transform, unable to compute output bounds.
