Records a set of pointer events that happened recently.
This class is usually used only in the data graph, to transmit the recent pointer presses, but it may be used anywhere a list of PointerEvents is desired.

double PointerEventList::match_pattern | ( | const string & | ascpat, |
double | rot, | ||
double | seglen | ||
) |
This function is not implemented yet.
It is a work in progress. The intent is as follows:
Returns a nonzero value if the mouse movements match the specified pattern. The higher the value, the better the match. The pattern is a sequence of compass directions (ie, "E", "NE", etc) separated by spaces. If rot is nonzero, then the pattern is rotated counterclockwise by the specified amount before testing. Seglen is the minimum length a mouse movement needs to be in order to be considered significant.

double PointerEventList::total_turns | ( | double | sec | ) | const |
returns the total angular deviation that the trail has made in the specified time period.
A small number means that the trail is moving in a relatively straight line, a large number means that the trail is zig-zagging or spinning. The result is in degrees.
