2001-05-25 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/scan_convert.[ch]: removed. * app/core/Makefile.am * app/core/gimpscanconvert.[ch]: added. Changed all function names and use GimpVector2 instead of ScanConvertPoint. * app/base/base-types.h: removed ScanConvertPoint (didn't belong here anyway). * app/pdb/tools_cmds.c * app/tools/gimpfreeselecttool.[ch] * app/tools/gimpiscissorstool.c * tools/pdbgen/pdb/tools.pdb: changed accordingly.
