              Some nice debugging by the client.

              From a specification point of view I think ICEpdf and the Apple viewers are behaving correctly. Generally speaking each line segment should be followed by S or s token to define a stroke. The following note is in the specification:

              Section 8.5.3.3, "If a subpath is degenerate (consists of a single-point closed path or of two or more points at the same coordinates), f shall paint the single device pixel lying under that point; the result is device-dependent and not generally useful. A single-point open subpath (specified by a trailing m operator) shall produce no output."

              The above quote would seem to backup the idea that we shouldn't be painting anything.
