Example doesn't run successfully

[doinkythederp]

I wasn't able to get the all_examples3 binary to run. It panics with this error on startup:

$ cd examples3d
$ cargo run --bin all_examples3
wgpu error: Validation Error

Caused by:
    In a RenderPass
      note: encoder = `<CommandBuffer-(1, 2, Metal)>`
    In a pass parameter
      note: command buffer = `<CommandBuffer-(1, 2, Metal)>`
    attachment's sample count 2 is invalid


thread 'main' panicked at 'Handling wgpu errors as fatal by default', [...]/wgpu-0.7.1/src/backend/direct.rs:1896:5

After doing a small amount of research it seems related to MSAA levels.
