Uses new material system for appearance
Each feature object now has a property called ShapeMaterial that
describes its physical properties. If it has a shape, it has a
material.
The ShapeColor attribute is replaced by a ShapeAppearance attribute.
This is a material list that describes all appearance properties, not
just diffuse color. As a list in can be used for all elements of a
shape, such as edges and faces.
A new widget is provided to allow the user to select materials in a
consistent fashion. It can also launch the material editor with its
more advanced capabilities.
Adds a checkbox to output a G85 cycle used for reaming or boring. The
cycle is like a normal drilling op, but feeds back out of the hole
instead of performing a rapid move.
G85 does not support peck or dwell, so those other options are disabled
when the "Feed retract" option is enabled in the UI.
