I think LCL has many CompareNNNN funcs, but misses func for TPoint. Here
it's comparing x/y screen coordinates
Why not extend TPoint with an IsEquals() method, so you can do something
like
var
p1: TPoint;
p2: TPoint;
begin
// ... populate p1 & p2
if p1.IsEquals(p2) then
// do something.
ComparePoints() returning a Integer is not a very friendly return type
either, whereas Boolean makes more sense.
First start by defining what ComparePoints is supposed to measure or compare.
If "equals" is needed, why not simply use p1=p2 ?
