ES31: Add link validation on MAX_COMBINED_SHADER_OUTPUT_RESOURCES This patch adds the link validation on the maximum combined shader output resources required in OpenGL ES 3.1 SPEC. OpenGL ES 3.1 SPEC has restrictions on the sum of the number of all active images, shader storage blocks and fragment shader outputs. A link error will be generated if this sum exceeds the implementation- dependent value of MAX_COMBINED_SHADER_OUTPUT_RESOURCES. In order not to affect the existing image tests, this patch also sets a temporary value for maxCombinedShaderOutputResources on D3D11 back-ends. We will set more accurate values for all the UAV related resource limits in the next patch.

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.
