[Lazarus] ComparePoints func

[Sandro Cumerlato]

What do you think about:

function ComparePoints(P1, P2: TPoint): TPoint;
begin
  Result.X := (P1.X - P2.X);
  Result.Y := (P1.Y - P2.Y);
end;

Best regards.

I think LCL has many CompareNNNN funcs, but misses func for TPoint. Here
it's comparing x/y screen coordinates

function ComparePoints(P1, P2: TPoint): integer;
begin
  if (P1.X=P2.X) and (P1.Y=P2.Y) then exit(0);
  if (P1.Y>P2.Y) then exit(1);
  if (P1.Y<P2.Y) then exit(-1);
  if (P1.X>P2.X) then exit(1) else exit(-1);
end;
