Mesh with VertexAttribute.Position format set to Float16 does not receive any projection from the Projector
How to reproduce:
1. Open the user's attached "ProjectorFloat16-2020.1.zip" project
2. Open the "SampleScene" Scene
3. Observe the meshes in the Scene view
Expected result: Both meshes with Float16 and Float32 positions receive shadows from the Projector
Actual result: Left mesh with Float32 position receives shadows, Right mesh with Float16 position does not
Reproducible with: 2019.4.3f1, 2020.1.0b15, 2020.2.0a17
Could not test with: 2018.4.24f1 (VertexAttributeDescriptor not available)
Notes:
- The issue is reproducible in the Editor and on Windows, Mac build
- The issue is reproducible with both Projector/Light and Projector/Multiply materials

Resolution Note:
By design, user code was constructing vertex data with w=0 values for the position, and some shaders (Projector one of them) do not expect that. Fixing code to produce w=1 values fixes it.
