I do not think that GDAL folks would change the GetRasterStatistics
function prototype since changing it would result in breakage of
binary compatibility. The best approach is to post your idea on
gdal-dev list and to get some suggestions how to proceed. Since this
would require an addition to GDAL API (e.g. a new function
GetRasterStatisticsWithFeedback) you would probably need a prepare
short RFC for that feature and get it approved - otherwise the new
feature will likely not get into GDAL.
