"Screen position out of view frustum" errors when Camera's frustum is very narrow and it intersects any GameObject mesh
How to reproduce:
1. Open the attached project "case_1147040-CameraViewportErrors" and scene "testScene"
2. Hover the GameView
3. Observe the Console Window
Expected result: no errors in the Console Window
Actual result: error messages containing string "Screen position out of view frustum" are printed to the Console Window
Reproducible with: 2017.4.26f1, 2018.3.13f1, 2019.1.0f2, 2019.2.0a12
Note: the issue only happens when the Camera's Viewport Width or Height is very close to zero. This can be achieved by setting the "Viewport Rect X" or "Viewport Rect Y" fields on the Camera Component to 0.9999 or even closer to 1 so the scene is almost completely out of view or setting the "Viewport Rect W" or "Viewport Rect H" to 0.0001 or closer to 0. The errors are reprinted when the Game View is visible and a new intersection with a Scene GameObject's mesh occurs or when the Game View is hovered

Resolution Note:
Setting the viewport to such small numbers is not advised, especially with these numbers it will be smaller than a pixel, at which point a lot of systems will start to complain, ideally you would want to disable the camera before this point or make sure you are at a size where you have at least a pixel being returned.
