public class VkPhysicalDeviceSubgroupSizeControlProperties
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing the control subgroup size properties of an implementation.
Description

If the VkPhysicalDeviceSubgroupSizeControlProperties structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to GetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

If VkPhysicalDeviceSubgroupProperties::supportedOperations includes SUBGROUP_FEATURE_QUAD_BIT, minSubgroupSize must be greater than or equal to 4.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SUBGROUP_SIZE_CONTROL_PROPERTIES
