We add a novel multiview multisampling extension that includes the
requirement to explicitly resolve the multisampled framebuffer. The
explicit resolve is much more straightforward to implement on top of
OpenGL and D3D11 than implicit resolve found in the native extension
OVR_multiview_multisampled_render_to_texture. It also has predictable
performance characteristics.
The extension allows multiview drawing to 2D multisample texture
arrays and is now enabled on both the GL backend and the D3D11
backend. The implementation is fairly simple, as it involves just
small changes in validation to allow multisampled framebuffer
attachments. The multiview rendering logic is exactly the same
regardless of whether multisampling is enabled.
For the most part the same tests are used to test both multisampled
and non-multisampled rendering. The tests will use a different
framebuffer setup depending on the test param. They resolve the
multisampled framebuffer to a non-multisampled framebuffer prior to
any readbacks from the framebuffer.
Some of the tests are adjusted so that they have the correct sub-pixel
positioning of multisampled quads, so there won't be any pixels that
would be just partially covered.
The tests don't have any tolerance for partially covered pixels - if
we find any platforms where the tests run into a sub-pixel positioning
corner case, tolerance may need to be added later.

We can just expose OES_texture_storage_multisample_2d_array instead.
The compiler was already changed to accept
OES_texture_storage_multisample_2d_array, and now the change is made
also at the API level.
Out-of-bounds access guarantees provided by ANGLE were the only big
difference between the ANGLE spec and the OES spec, so it's simpler
to just expose the native extension. Safe out-of-bounds accesses can
be guaranteed without having them in the extension spec.
This also adds missing texStorage3DMultisample entry point to the proc

This is needed for antialiased multiview rendering.
The extension is written against OpenGL ES 3.1. To add support for it
in OpenGL ES 3.0, an extension for exposing non-array multisample
textures will also be required (ANGLE_texture_multisample). This has
been previously proposed though not yet submitted to ANGLE.
The extension spec provides robustness guarantees for sampling
multisample textures. It still needs to be tested whether native
implementations follow these guarantees or if the spec needs to be
adjusted to allow for clamping coordinates. The native
KHR_robust_buffer_access_behavior is not very explicit about whether
the texel fetch robustness applies also to multisample textures.

Whenever the swap chain is tested for needing a resize, surfaces with
mFixedSize are treated as if they should be resized to mFixedWidth and
mFixedHeight from their current size. This way fixed-size surfaces

This guarantees compatibility between different compiler versions that

optimizations. It follows the spirit of GLSL ES 3.00.6 spec section

The implementation is fixed to correctly follow the spec. When

The extension increases the flexibility of the API compared to plain

Internally this sets the ANGLE format of the buffer. There are new

When a EGL pbuffer is created based on a D3D SRGB texture using
EGL_ANGLE_d3d_texture_client_buffer, SRGB conversions are performed as
if it was an SRGB surface. The value of EGL_GL_COLORSPACE now
reflects that correctly. If the pbuffer is bound to a texture and used
as a framebuffer attachment, querying GL_FRAMEBUFFER_COLOR_ATTACHMENT
also reflects that correctly.
The behavior is the same on both the D3D backend, where there is no
native interop involved, and on the GL backend using
WGL_NV_DX_interop(2).
There are a few limitations on the GL backend that relies on native
interop:
1. SRGB conversion for textures created this way can't be disabled
using the GL_FRAMEBUFFER_SRGB_EXT toggle that's exposed in ANGLE
through EXT_sRGB_write_control. This is now documented in the
EGL_ANGLE_d3d_texture_client_buffer spec. On the D3D backend this is
not a problem since EXT_sRGB_write_control is not supported either
way.
2. Creating a pbuffer out of a D3D11 texture with the format
DXGI_FORMAT_B8G8R8A8_UNORM_SRGB does not work, even though it was
listed as one of the supported formats in the
EGL_ANGLE_d3d_texture_client_buffer spec. It's now mentioned that
support for this format is optional.
