    Capture/Replay: Only convert GLES 2 GLenums to string.
    
    Previously the enum conversion script would convert all enums in gl.xml
    including those for desktop GL. When replaying from a CPP file we would
    sometimes try to use enum values that only are exposed in desktop GL.
    
    One example is GL_TEXTURE_MAX_ANISOTROPY/GL_TEXTURE_MAX_ANISOTROPY_EXT.
    GLES only has the "EXT" version. Desktop uses the core version. This
    was breaking a replay sample that used the EXT enum.
    
    Fix this by a) including the anisotropy extension in registry_xml and
    b) updating the enum script to only parse GLES 2 entries. In the future
    we could improve the situation by auto-generating a header that defines
    exactly the enums we need for ANGLE.
    
    Also updates the enum helper to use uppercase enum values.

  • ANGLE - Almost Native Graphics Layer Engine

    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.
