Research direction

Start with the H3 Java polyfill API and reproduce the boundary case described in the issue, using the attached image as the only example provided. Trace how polygon centers and boundary areas are classified, then verify that the previously skipped boundary region is included without breaking other polyfill results.

Description

Hi I have noticed, when using polyfill for a polygon, it randomly skips certain areas near the boundary. How can we solve this?

For example. In this image blue dots are polygon side, and red is center. Notice the area in Cayote Point is not part of any polygon. So, polyfill will skip it even if that is part of the boundary.

Seems like if center is not part of boudary, it skips the whole polygon.
