EXTShaderImageAtomicInt64 (LWJGL 3.3.1 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.EXTShaderImageAtomicInt64

```
public final class EXTShaderImageAtomicInt64
extends java.lang.Object
```
This extension extends existing 64-bit integer atomic support to enable these operations on images as well.
When working with large 2- or 3-dimensional data sets (e.g. rasterization or screen-space effects), image accesses are generally more efficient than equivalent buffer accesses. This extension allows applications relying on 64-bit integer atomics in this manner to quickly improve performance with only relatively minor code changes.

64-bit integer atomic support is guaranteed for optimally tiled images with the FORMAT_R64_UINT and FORMAT_R64_SINT formats.
