C# Class kOS.Suffixed.VectorRenderer

Make all vector renderers invisible everywhere in the kOS module.

Move the origin point of the vector drawings to move with the current ship, whichever ship that happens to be at the moment, and move to wherever that ship is within its local XYZ world (which isn't always at (0,0,0), as it turns out.):

Calculates colors and applies transparency fade effect. Only needs to be called when the color changes.

Assign the arrow and label's positions in space. Call whenever :VEC, :START, or :SCALE change, or when the game switches between flight view and map view, as they don't use the same size scale.

Update camera data, abstracting the different ways KSP does it depending on view mode:

Update _shipCenterCoords, abstracting the different ways to do it depending on view mode:

Get the position in screen coordinates that the 3d world coordinates project onto, abstracting the two different ways KSP has to access the camera depending on view mode. Returned coords are in a system where the screen viewport goes from (0,0) to (1,1) and the Z coord is how far from the screen it is (-Z means behind you).

Place the 2D label at the correct projected spot on the screen from its location in 3D space:

Position the origins of the objects that make up the arrow such that they anchor relative to current ship position.
