Custom Border Colors

VkSamplerBorderColorComponentMappingCreateInfoEXTStructure specifying the component mapping of the border color

Custom Border Color Registration

When using descriptor heaps, it is possible to create a sampler descriptor without creating a sampler object. Without this object, implementations using a fixed palette of border colors have no way to know which custom border colors are active or not.

In order to use custom border colors with descriptor heaps, border colors must instead be registered with the implementation and unregistered when they are no longer in use, and the registered index provided when writing the sampler descriptor.
