I ran this through 'guix style' ...

> +entrypoints required to use Vulkan without linking to vulkan-1.dll or
> +statically linking Vulkan loader. Additionally, volk simplifies the use of
> +Vulkan extensions by automatically loading all associated
> +entrypoints. Finally, volk enables loading Vulkan entrypoints directly from
> +the driver which can increase performance by skipping loader dispatch
> +overhead.")

... and simplified the description somewhat, + added two spaces after
sentences ('guix lint' should warn about this).
