Allow creating EGL pbuffers from typeless D3D textures A new extension EGL_ANGLE_d3d_typeless_texture_client_buffer is added that allows creating EGL pbuffers from typeless D3D textures. The extension increases the flexibility of the API compared to plain EGL_ANGLE_D3D_texture_client_buffer. The colorspace for the created EGL pbuffer can be set by using the EGL_GL_COLORSPACE attribute. Internally this sets the ANGLE format of the buffer. There are new ANGLE formats that are used specifically for typeless textures, separate ones for SRGB and linear views into the D3D textures. The extension is only supported on the D3D11 backend of ANGLE.

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.
