...mostly done with a rewriting Clang plugin, with just some manual tweaking necessary to fix poor macro usage. Change-Id: I71fa20213e86be10de332ece0aa273239df7b61a

This primitive provides a view-dependent helpline definition. The Helpline
|
|
is defined by a line equation (Point and vector) and a style. When the style
|
|
is a line, dependent from Viewport the visible part of that Helpline is
|
|
constructed. For Point, a cross is constructed. This primitive is highly
|
|
view-dependent.

The visualisation uses the two given colors to create a dashed line with
|
|
the given dash length.
