This test will load traces and cycle through a set of frames.

The new tests are:

    TracePerfTest.Run/gl_trex_200_210
    TracePerfTest.Run/gl_trex_800_810
    TracePerfTest.Run/gl_trex_900_910
    TracePerfTest.Run/gl_trex_1300_1310

To download the traces, you must be granted access and authenticate
with the cloud.  See the steps in RestrictedTraces.md for this.

Then add the following to the end of your .gclient file:

    "custom_vars": {
      "checkout_angle_internal":"True"
    },

And run `glcient runhooks`.

To enable building the test, add the following GN arg:

    build_angle_trace_perf_tests = true

See the new markdown document for ways to execute the tests.

This initial prototype introduces a new feature to the Vulkan back-end
that disables the deferred command recording. The intent is to have a
lower CPU overhead during submission calls which currently walk a DAG.

The feature is not complete. Currently it only passes the ANGLE
SimpleOperationTests. Moreover it is extremely simple and only allows
use of one command buffer at a time. In the future we'll allow open
command buffers for recording outside and inside render pass commands
at the same time. We'll also support collapsing RenderPasses together
for some use cases.

Currently the prototype only passes "SimpleOperationTest". There are
quite a few unimplemented features like queries, XFB, etc.

Currently Windows on ARM doesn't support OpenGL but it is enabled in ANGLE by default.
Vulkan is only supported via Swiftshader so we should not test native Vulkan.
Therefore it causes crashes and fails on Windows on ARM when running angle_end2end_tests.

According to the latest change in WebGL's OVR_multiview2 spec, the GL_OVR_multiview should NOT be defined. Refer to https://www.khronos.org/registry/webgl/extensions/OVR_multiview2/

I.e. this shader should NOT fail compilation:

#version 300 es
#extension GL_OVR_multiview2 : require
#ifdef GL_OVR_multiview
    #error legacy GL_OVR_multiview support must be forbidden
#endif

Apple doesn't support GL_KHR_robust_buffer_access_behavior, so we don't
know if we can trust the driver to be safe with out of bounds array
accesses. It's not currently failing the out of bounds access tests, but
this may be coincidental. In general it makes sense to always clamp
array accesses when GL_KHR_robust_buffer_access_behavior is not
supported.

The validating command decoder actually enables this workaround
unconditionally, but that seems unnecessary.

Inactive vertex attributes are harmless to remove.  Between two
consecutive stages, the input varyings must be a subset of the previous
stage's output varyings.  This means removing inactive input varyings is
also harmless.

Removing inactive output varyings is not possible though.  GLSL allows a
varying to not be written by the previous stage even if it's used in the
current stage (values will be undefined, but it's not an error).  This
means that an inactive output varying may still need to exist as part of
the shader interface in case the following stage has that varying as
input (and is active).

instead of a preprocessor condition.  This means drawing both triangles

The non-float variations of the mix builtin were conditioned to desktop
GLSL, but they are present in ESSL 3.1+.  This change also implements
constant folding of these builtins as exercised by dEQP.

Accidentally submitted a patch set without requested changes. This

All device extension features and properties queries are now performed
in a single call for each (i.e. one for features, one for properties),
with all the extension structs chained.  Then based on which feature is
present (not just whether the extension is supported), the extensions
and features are enabled.

In the process, it fixes the following issues:

- If VK_EXT_vertex_attribute_divisor is present, but the necessary
vertexAttributeInstanceRateDivisor feature is not supported, that
feature is not enabled and the emulation path is taken.  Incidentally,
this also fixes an issue with renderdoc that refuses to replay captures
on such devices.
- If VK_EXT_transform_feedback is present, but the necessary
transformFeedback feature is not supported, similarly that feature is
not enabled and the emulation path is taken.
