dotCooCoo 138e9ca466 Paths: a curve with a handle near f64::MAX is measured by its control points
PathData::bounds measured each segment by its start, end and extrema,
as kurbo's bounding_box does. For a curve with a handle at about 1e308
in size, or an infinite one, kurbo's extrema computation overflows and
drops the extreme. The box then held only the anchors. The canvas check
after an edit reads that box for the selected objects, so path.create
kept a curve with handles at 1e308.

The new segment_bounds measures a segment by its control points when
one of them has an x or y that is infinite or larger in size than
f64::MAX / 16, and by its extrema otherwise, bit for bit as before.
curve_bounds joins those boxes as kurbo does, and PathData::bounds uses
it, so such a curve's box holds the whole curve and the canvas check
refuses an edit that leaves one selected.
