Remove 16× MSAA support due to driver bugs and low performance
In the `master` branch, 16× MSAA caused the entire system to freeze
on NVIDIA GPUs. This is likely caused by graphics drivers not actually
implementing 16× MSAA, but combining 8× MSAA with 2× SSAA instead.
On top of that, modern shader complexity makes 16× MSAA very difficult
to use while keeping a good framerate. 8× MSAA is hard enough to use
as it is.
