The issue was caused by an internal error in the edge processor.
Effectively the weak attractor scheme was causing this problem.
As the weak attractors are making things worse rather than
better I dropped them.
In theory, the weak attractors render an edge undisturbed by
neighboring intersection points, but in cases or parallel edges
this lead to problems: omitting cut points violates the output
edge configuration warranties the the polygon stitcher fails.
In addition, to maintain the solution for bug #74, the cut point
capture condition was relaxed, so that edge crossing the exact
corner of the snapping rectangle of a point are not considered
captured.

One internal enhancement: progress adaptors can be
instantiated temporarily now to catch progress events.
Issue was: the asynch interface for HTTP access
wasn't entirely compatible between Curl and Qt
implementations.
Plus, the progress integration was messed up
because of the deleteLater scheme (progress was
visible even after the connection ended).
The deleteLater scheme was replaced by an
explicit close which does not require the
connection to be deleted immediately in the
receivers.
Reason: the timer involved measured CPU time. So if the
process wasn't CPU intensive (i.e. waiting for network
response), cancelling the operation wasn't possible.
Reasoning: on Qt <4.7, custom request are not available.
They are required however to implement WebDAV. libcurl
provides a substitute for QNetwork. This is important
for deployment on CentOS6 for example.
* "keep layer name" will not try to modify layer names into
GDS layer/datatypes. The feature is available in the DXF
reader options and for the buddy scripts as "--keep-layer-names"
It applies to CIF too.
* "contour accuracy": when merging lines into contours, this
accuracy is applied to find neighbors. By default this value
is 0. If set to a value >0, points with distances (square
metrics) less than this value will be connected.
The buddy script option is --dxf-contour-accuracy=value.
