edgeNudge関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
How far to move the view in a frame for a finger at (px, py) of a box: the board moves the other way, toward the finger. It is gentle: nothing
at EDGE pixels from a side, rising in a line to EDGE_STEP pixels a frame at the side itself, so a finger that only brushes the edge
of the box moves the view hardly at all, and one held at the very edge moves it steadily.
