/**
 * Structure describing sample location limits that can be supported by an implementation.
 * 
 * Description
 * 
 * 
 * {@code sampleLocationSampleCounts} is a bitmask of {@code VkSampleCountFlagBits} indicating the sample counts supporting custom sample locations.
 * {@code maxSampleLocationGridSize} is the maximum size of the pixel grid in which sample locations can vary that is supported for all sample counts in {@code sampleLocationSampleCounts}.
 * {@code sampleLocationCoordinateRange}[2] is the range of supported sample location coordinates.
 * {@code sampleLocationSubPixelBits} is the number of bits of subpixel precision for sample locations.
 * {@code variableSampleLocations} indicates whether the sample locations used by all pipelines that will be bound to a command buffer during a subpass must match. If set to {@link VK10#VK_TRUE TRUE}, the implementation supports variable sample locations in a subpass. If set to {@link VK10#VK_FALSE FALSE}, then the sample locations must stay constant in any given subpass.
 * 
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code sType} must be {@link EXTSampleLocations#VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SAMPLE_LOCATIONS_PROPERTIES_EXT STRUCTURE_TYPE_PHYSICAL_DEVICE_SAMPLE_LOCATIONS_PROPERTIES_EXT}
 * {@code pNext} must be {@code NULL}
 * 
 * 
 * If the {@link VkPhysicalDeviceSampleLocationsPropertiesEXT} structure is included in the {@code pNext} chain of {@link VkPhysicalDeviceProperties2KHR}, it is filled with the implementation-dependent limits.
 * 
 * See Also
