 Hi all, actually ST_Clip does not always return all the pixels that
 intersect with the geometries, I think would be great to have a param to
 be able to select all the pixes that the geometry touches.

 I was thinking initially, a param to "if_touches = true", but then... what
 happens if in the future there is other implementations of how to select
 pixels? for that, maybe is good to have a param like "method" to choose
 the one we want to use.

 No idea which would be the best case, because I don't know if there is a
 simpler way to send custom params to all the "methods" that can be
 developed.

 But maybe this last part is a separate issue, I just think is good to have
 consideration on it.

 Thx!
