When overridden in a derived class, updates the raster data associated with the raster stream at the specified time. When the Update method is called, the raster stream contains a raster data buffer defined by the current Attributes of the stream for updating the raster data. The time parameter provides the current and next Scene Manager time. Return true if the raster data was updated, otherwise return false.
