Revert "Allow enabling trace annotations" This reverts commit f094bac949922dabc3dd6944f3dec04111e953b6. Reason for revert: Causes timeouts on Debug bots in the BufferDataTest.NULLData Original change's description: > Allow enabling trace annotations > > Tracing was never allowed to happen because getStatus always returned > false. Also want to allow tracing for release builds for perf analysis. > > Bug: angleproject:3176 > Change-Id: I7aa94ed9fe3d7f67fe6dd10123c9badc7fb49d82 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1475248 > Commit-Queue: Courtney Goeltzenleuchter <courtneygo@google.com> > Reviewed-by: Jamie Madill <jmadill@google.com> TBR=ynovikov@chromium.org,geofflang@chromium.org,jmadill@google.com,courtneygo@google.com # Not skipping CQ checks because original CL landed > 1 day ago.

The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.
ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.
Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
