sw rendering won't benefit from vulkan very much, in fact it would be
worse than GL in some cases, as Vulkan really works on the building up
long command buffers and executing them, rather than direct execution in a
context that GL does.
But eventually there will be Vulkan-only software and some fallback is
needed for the hardware not supported by any hardware driver.
