Detailed Description

Specifies the points to modify in an existing page item.

For Modify path and Remove path point commands, all arguments are used. For Add point commands, only SetStartingIndex and SetPathIndex are used. In the Add case the starting index indicates the place the cmd should insert before. i.e if index is 4 the add cmd inserts before index 4. If the index is -1 the add command appends the new points. If the pathIndex is equal to the current number of paths the cmd creates a new path. If pathIndex is -1 add points creates a new path, appends the points to the new path, and returns the new index via this interface (it changes pathIndex). If the number of points to add is zero in the path geometry interface of the command, then add points simply creates a new path with no points.

If both startingIndex and pathIndex are equal to -1, then add points appends all of the paths and points from the command to the pageitem.
