Device groups can be used to:
- only render on certain physical devices, using a device mask
- only allocate memory on certain physical devices, using a
device mask
- distribute rendering across different physical devices,
using different render areas for each physical device
SwiftShader only supports a single physical device, so most of
these settings can simply be ignored.
