DESCRIPTION:

Eccet generates pictures from input data. To achieve that, it
runs one or more renderers on the data that will each generate
a picture from the volume(s) that are currently loaded.
These pictures are then combined and additional objects like
/spline/s, tristrips and markers are embedded to finally
produce the output. This output is then plotted into a window
that is called a "view".

In a more precise sense a view also encompasses all data that
was used to generate the view and which is common between
/renderer/s. This inlcudes the camera which is attached to
the view, data lines, view size and scale, it's position and
z-ordering on the windowing system, etc.

Views can look into a different direction than the camera they
are attached to. This is done using VIEW_OFFSET and VIEW_TURN.
