Fix EGLSyncControlTest.SyncValuesTest timeout on Windowse Server 2012 R2 The test does two buffer swaps and polls sync values waiting for sbc (swap buffer counter) value to first increase from 0 to 1, then from 1 to 2. Looking the error log I see that sometimes it fails on the first wait and sometimes on the second wait. Also the total runtime varies between 1000 and 1600 ms. That makes me think that perhaps test doesn't poll long enough to run reliably on a test machine. I've increased the number of poll iteration to 500 and the sleep between iterations - to 10 ms (I think in reality it was 10 ms already because the previously used 1 ms is only possible with high resolution system timer).

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.
