EXTBorderColorSwizzle (LWJGL 3.3.1 - Vulkan)

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

```
public final class EXTBorderColorSwizzle
extends java.lang.Object
```
After the publication of VK_EXT_custom_border_color, it was discovered that some implementations had undefined behavior when combining a sampler that uses a custom border color with image views whose component mapping is not the identity mapping.
Since VK_EXT_custom_border_color has already shipped, this new extension VK_EXT_border_color_swizzle was created to define the interaction between custom border colors and non-identity image view swizzles, and provide a work-around for implementations that must pre-swizzle the sampler border color to match the image view component mapping it is combined with.

This extension also defines the behavior between samplers with an opaque black border color and image views with a non-identity component swizzle, which was previously left undefined.
