Do you talk abound rounding effects?

That may have been it.

I remember some flickering effects myself when setting float bounds to the SystemWindowMorph, but I could not reproduce it; apparently, someone has added a check.

Also, Morphic is not the only client of Rectangles, is it?

Actually, I believe it is.  Sure, other domains can and do use it but, IIRC, it has a distinct "screen" layout, where "topLeft" is 0,0 instead of bottom left as in Cartesia.  Accidentally swapping the two points; (e.g., as in, bottomRightPoint corner: topLeftPoint) will also break things.

For example, LayoutFrames explicitly depend on floats.


Or what issue are you talking about else? :)

I don't recall, sorry.

Be careful about using non Integers with Rectangles, too.  As with Intervals, I think I remember that some of the API will break.

Add Rectangle>>#pointAtFraction:

Example: [(5@5 rect: 10@20) pointAtFraction: 0.5@1] will give you 7.5 @ 20.
