It now uses rsvg_handle_get_geometry_for_layer() instead of rsvg_handle_get_(position|dimensions)_sub() which have been deprecated in favor of the new function which returns accurate (double) positioning and size. Back when I first made this build tool, librsvg had several blocking bugs to make icon extraction work properly. This seems to improve nicely. Nevertheless I still don't build this tool because after testing, more bugs remain and icon extraction is still not right. Just updating the code to undeprecate it but leave the build commented out for now. ;-( See librsvg#134, librsvg#128 and librsvg#250 for bug reports following these issues.
