The PR above fixes the issue for the perspective camera only. The orthogonal one still remains broken. |

# Objective - Fixes bevyengine#4005 ## Solution - Include the `near` and `far` clipping values from the perspective projection in the `Camera` struct; before that, they were both being defaulted to 0.

# Objective - Fixes the issue with orthographic camera imported from glTF not displaying anything (mentioned in #4005). ## Solution - This was due to wrong scaling mode being used. This PR simply changes WindowSize scaling mode to FixedHorizontal. ## Important Note Currently, othographic scale in Blender, three.js, and possibly other software does not translate to Bevy (via glTF) because their developers have [misinterpreted the spec](KhronosGroup/glTF#1663 (comment)). The camera parameters have been clarified in glTF 2.0, which was released on October of 2021. In Blender 3.0.1 this issue has **not** been fixed yet. If you are importing orthographic cameras from Blender, you have to divide the scale by 2.

Added a GLTF scene with a camera and light in it.

What actually happened
The world appears to be unlit:
Additional information
The orthogonal camera is completely broken as well: it does not output anything at all. The reason for that might be more complex, because the fix suggested for the perspective camera does not apply to this case.
