 It would be nice to be able to enforce an optional parameter in qgm as
 obligatory - sth like a "require=yes" atribute.

 Case: r.cost supports various input types - x,y coords, vector map, raster
 map. According to GRASS toolbox convention, I guess it should be divided
 into 3 seperate ones qgms: r.cost.coord, r.cost.vect, r.cost.rast.
 Although in each case the respective input starting points method should
 be required, there is no way to specify this in a qgm currently.

 #3203 is related - maybe to workaround that bug add support for sth like
 "require=no" BTW?
