Fix ambiguous function call issues in HLSL output D3D compiler can't resolve between these overloaded functions: float4 vec4(float2x2 x0); float4 vec4(float4 x0); Include the parameter types in the function name to disambiguate between overloaded user-defined functions and constructors, like this: float4 vec4_float2x2(float2x2 x0); float4 vec4_float4(float4 x0); This is only done for float2x2 and float4 parameters, other parameter types like float2x3 vs. float3x2 don't need this.

#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 to desktop OpenGL, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES 3.0 to all of these APIs is nearing completion, and future plans include enabling validated ES-to-ES 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.
