is_collinear for the first endpoint of L is now unified and is always equal to FALSE.
Add tests of is_collinear. It is tested by passing 4th and 5th char in the expected turn string (= means collinear, + means non-collinear), e.g. "mxi=+" for L/L means that L1 ends in this IP and was collinear before meeting the Point, L2 is going "inside" intersection and wasn't collinear before.
Replace method_and_operation_replacer with turn_transformer.
relate_linear_areal:
handle non-endpoint x-c turns pair generated for a collinear spike.
relate/follow helpers:
fix turn_on_the_same_ip to use fraction instead of dimension.
get_turns:
L/L and L/A - use base_turn_handler::assign_point() to set fractions properly for collinear-opposite spikes.
L/A - fix the condition in calculate_spike_operation() used to check if a spike goes into the interior or exterior.
Some asserts are invalid when 'x' operation can be somewhere in the middle (boundary_checker).
boundary_checker::is_boundary() function removed since it's not used anywhere.
Errors in get_turns are related to the handling of touches turn. t,i/i must be handled and is_collinear must be set in operations for spikes.
2 Turns are generated for a spike, one with operation_blocked the second one with operation_intersection.
relate_linear_linear is not working yet, for now it is only ensured that boundaries will not be checked for those turns, which would result with assert failure.
TODO: opposite collinear and equal, touches c/c and endpoints intersecting a spike + the adaptation of relate(L,L).
Change the ignoring check calculation in get_turn_info_for_endpoint.
Add additional parameters to the second version of collinear_opposite<>::apply() defining if the pk and/or qk are valid (in other words current segment is NOT the last one).
Also make ignoring check for last endpoint in L/A more clear.
In this case no sections were generated for those "empty" Linestrings but if there were some sections already generated they could be marked as last_non_duplicated.
add info about the first/last non-doubled section to sectionalize
modify get_turns() to pass info about the first/last segment to TurnPolicy::apply()
modify parameters of TurnPolicy::apply()
add searching for the next non-equal point in relate L/A when the segment of Linear must be checked if it starts in the interior or exterior of the Areal
add tests for relate and within
add relate L/A to Jamfile
