[Gdal-dev] Support for transforming between pixel/line raster space, and projection coordinates space

Hi All,

Would it be acceptable to support a separate class for the
transformation between the pixel/line raster space, and projection
coordinates space? Currently - at the SWIG API - the Dataset
GetGeoTransform / SetGeoTransform operates on a double array with 6
elements containing the affine transformation coefficients. Having an
own GeoTransform quits a lot of
headaches and helps centralizing the code of calculating the xy coordinates
in pixel and in projected space. In general, the interface should be
obvious, clear and self describing.

Having a substantial support on this idea it would be quite an easy to
proceed with and RFC describing the necessary changes to implement
this feature.

Best regards,
