@foreach

Calls func for every operation of the path.

Note that this may only approximate this, because paths can contain optimizations for various specialized contours, and depending on the flags, the path may be decomposed into simpler curves than the ones that it contained originally.

This function serves two purposes:

• When the flags allow everything, it provides access to the raw, unmodified data of the path.
• When the flags disallow certain operations, it provides an approximation of the path using just the allowed operations.

Parameters:

this	a path
flags	flags to pass to the foreach function
func	the function to call for operations
user_data	user data passed to func

Returns:

false if func returned false, true otherwise.
