which essentially means some cleanup and no more regressions: - add state POINT_BOTH for moving the entire line - use the move cursor for moving the entire line - reorder some functions - set the tool to handle click events - make clicks and no-motion releases behave properly - #if 0 the code for "shapeburst handles", they don't work yet - return to gimp:shapeburst until we have figured progress for GEGL ops - indentation, stuff...
