Arguments: position center-position radius
Returns whether position is inside the circle that is defined by center-position and radius. position should be a position instance (as created with make-position), center-position should be a position that specifies the center of the circle, and radius should be a positive integer that specifies the radius.
This function is used internally by circular hotspot
s (see hotspot-region), but can be used by itself if
desired.
