cannot create curve with infinite size

Error message

cannot create curve with infinite size

What it means

Check in layout_curve: after building the curve from its components, the computed bounding size is infinite, so the curve cannot be laid out; usually a component coordinate resolves to infinity relative to an unbounded region.

Solutions

1. Use finite coordinates for all curve components
2. Place the curve inside a container with a definite finite size
3. Avoid fractional/infinite lengths in curve point and control-point coordinates
