oh boy, why create an oval item, when you need a single point? ;-)

Usually, ovals don't include the corner points used to place them.
a 1-sized oval could be expected to be one pixel on the canvas,
but it isn't. Actually it is drawn as 4 pixels, but what its
actual size is, can only be found by trial&error

% .c find overlapping 100.5 100 100.5 100
% .c find overlapping 100 100.5 10 100.5
both find the oval!

strangely, some other coordinates that I thought
would have to ly on the oval didn't, not even
when I used a filled oval.

I can't tell if this can be seen as a bug or not.
