According to my reading, shaderImageGatherExtended is required to use any offsets at all, even constant offsets less than 32: "shaderImageGatherExtended specifies whether the extended set of image gather instructions are available in shader code. If this feature is not enabled, the OpImage*Gather instructions do not support the Offset and ConstOffsets operands."
But `OpImage*Gather` also accepts `ConstOffset` (no 's'). That feature flag isn't needed to use the `ConstOffset` operand with `OpImage*Gather`.
