<div class="gmail_extra">Looks really good! I made a
comment earlier about how it would be good to add a
couple more #defines for these magic vertex buffer
handles. Also, now that things are working, I'd like to
re-confirm whether or not vertex buffer 33 works. If it
does, we should use it. If it doesn't, then I'm fine
with dropping the limit.<br>

<div>I had another thought on the buffer 33... Doing a
little digging through the docs, it appears that the
hardware only started supporting 34 vertex buffers on Sky
Lake but it has supported 34 vertex elements since Ivy
Bridge or even earlier. If we were somehow able to use
the same buffer for DrawID as we did for BaseVertex and
BaseInstance, we could keep the limit at 32. I'm not
seeing any real good way to do that in the indirect draw
case so let's go ahead and drop the limit to 31 for now
and figure out how to be more clever later.<br>

Just gave a try to buffer 33 on Kabylake, that didn't work :(<br>
So I think we're stuck with 31 for now.<br>
