* 2. How can we suppress fiducials such as those in the corners of the pic-programmer demo?
*
* 3. Export Graphics to Layer objects (see 3d_draw.cpp for clues) to ensure that custom
* tracks/fills/logos are rendered.
* module->TransformGraphicShapesWithClearanceToPolygonSet
*
* For mechanical correctness, we should use the following settings with arcs:
* 1. max. deviation: the number of edges should be determined by the max.
* mechanical deviation and the minimum number of edges shall be 6.
* 2. for very large features we may introduce too many edges in a circle;
* to control this, we should specify a MAX number of edges or a threshold
* radius and a deviation for larger features
*
* For example, many mechanical fits are to within +/-0.05mm, so specifying
* a max. deviation of 0.02mm will yield a hole near the max. material
* condition. Calculating sides for a 10mm radius hole will yield about
* 312 points; such large holes (and arcs) will typically have a specified
* tolerance of +/-0.2mm in which case we can set the MAX edges to 32
* provided none of the important holes requires > 32 edges.

* KNOWN BUGS:
* 1. silk outlines are sometimes mangled; this is somehow due to
* many overlapping segments. This does not happen in 3Dviewer
* so it is worth inspecting that code to see what is different.
*
* These artefacts can be suppressed for exploratory purposes by
* removing the line width parameter from the length calculation in
* export_vrml_line()
