Remarks
IPixelFilter2 is an optional interface for implementing a custom pixel filter. It will be called, if implemented, whenever the raster properties, including number of rows and columns, and extent, has changed, and right before a pixel block is to be filtered, with more information. A custom pixel filter can use the additional information to, for example, get the cellsize, and pre-fetch a related pixel block, and etc.
