[gdal-dev] Performance Issue with VRT Pixel Function and Large Number of Source Rasters

[Abdul Raheem Siddiqui]

Pull request here: https://github.com/OSGeo/gdal/pull/12178 There is
potentially more subelements that can go in this top level section but I
was not sure if they would work across all types of pixel functions.

P.S: Is there a reason why SkipNonContributingSources is False by default?
Wouldn't it make more sense to have it set to True by default?
