 > You are right, the patch lacks tests - it was just proof-of-concept. I
 will implement them in the next patch.

 The concept is proofed when the patch is working.

 With
 {{{
             /* get pixel coordinates defined by current region */
             pixel_start = (int) (cellhd.west - adfGeoTransform[0]) /
 adfGeoTransform[1];
             line_start = (int) (cellhd.north - adfGeoTransform[3]) /
 adfGeoTransform[5];
             pixel_end = (int) (cellhd.east - adfGeoTransform[0]) /
 adfGeoTransform[1];
             line_end = (int) (cellhd.south - adfGeoTransform[3]) /
 adfGeoTransform[5];
 }}}
 you cast the numerator of the division to int while `Rast_align_window()`
 uses `floor()` and `ceil()` for the equivalent calculations. Why?
