If you zoomed out and rotated, there were artifacts

If you zoom out (much), toggle the view and rotate the actor. There are artifacts.

My last update didn't actually compile

Fixed indentation

Reduced clipping RE phosit: The front of actor is cut-of.

Prefer default value to initialized value in AtlasViewActor

Deduplicated default value vs initialised value.
Values are placed in the constructor,
in line with other code in the project.

Implemented some helpful suggestions across multiple files

CCamera::ProjectionType::CUSTOM and
ScenarioEditor::ProjectionType::CUSTOM
are "not implemented". In switch statements,
they fall through to the default case, which is PERSPECTIVE

ScenarioEditor::ProjectionType
no longer "mirrors"
CCamera::ProjectionType.
There are no longer any changes to Camera.h
A switch statement is used to convert enum to int to enum.

"Mirroring" a type (union) is bad. I don't have a better solution though.

There was a line in AtlasViewActor::Render()
that I had commented out because it interfering with my code.
I felt that this was bad form.
I have updated that line with an if/else statement
To provide the functionality that I needed

I modified the formatting of the code to match the coding conventions

I fixed the glitch where the actor viewer wasnt updating
until you press the Toggle Perspective button

Instead of using a bool to store projection type, I used an enum.
I had to delare a new enum in
source/tools/atlas/AtlasUI/ScenarioEditor/ScenarioEditor.h

How about using ProjectionType from source/graphics
/Camera.h ?

A few incorrect comments that snuck past my guard in the previous upload.

I replaced references to 3d/2d projection with perspective/orthogonal prejection.

Removed printf
Removed printf statements used for debugging. Every second line has references to 2d/3d, where there should be references to perspective/orthogonal.
