[SDL] Patches to add support for Vulkan

[Jacob Lifshay]

I've implemented support for Vulkan by emulating Tizen's interface. The
patches are too big to send to this mailing list, so I've created a github
gist instead:
https://gist.github.com/programmerjake/71ae02e439ff20dca3b1bca6779211f8

I've implemented the driver for X11 using both XCB and Xlib. I also added a
test for Vulkan.

Any suggestions for how to improve this, why libsdl won't support vulkan,
or anything I forgot to do that's necessary to commit this?

No idea what the official stance regarding Vulkan is, but to ensure
patches aren't "lost" it's a good idea to create an issue at
https://bugzilla.libsdl.org/ and attach the patch there.

I don't know why you didn't get feedback, but probably the relevant
people (Sam and Ryan mostly?) are just busy - and this mailing list
hasn't been very active in the last weeks, so don't worry, it's not
specific to your patch :)

Anyway, I don't know much about Vulkan so I can't judge your code, but I
think SDL should support it, as it seems to gain traction, especially on
Linux.

Cheers,
Daniel

Very busy over here; I saw that the patch exists but I haven't had a
chance to look at it further, so I don't know what concerns I might have
with it yet, but getting _some_ sort of Vulkan support into SDL is on
the TODO list, so it's likely we'll at least start from your work if we
don't take it as-is.
