    • Vulkan: Support OVR_multiview and OVR_multiview2 · 5b314268
      Shahbaz Youssefi authored 
      Multiview is supported in Vulkan simply by specifying the number of
views in the render pass, and creating the appropriate image views.  A
number of changes to the way image views and render targets are stored
are made to support those that don't cover the entire range of layers.

One particular detail that is not implemented in this change is the use
of queries in combination with multiview.  Vulkan specifies that N
queries are actually produced (N being the number of views) which must
be summed by the application, but this is not currently done.

    • Vulkan: Unpack RenderPassDesc · 9bad7a19
      Shahbaz Youssefi authored 
      Upcoming multiview support needs to add 2~3 more bits to this struct,
but this struct is already fully packed.  As the combination with
emulated multisampled render to texture is not planned, some bits used
for MSRTT can be aliased with multiview.  However, that makes the
packing of this struct even more unwieldy.

Since only tens of render passes are expected per frame, increasing the
size of the render pass cache key should not have a dramatic effect.
