/**
 * Native bindings to the ANGLE_translated_shader_source extension.
 * 
 * WebGL uses the GLSL ES 2.0 spec on all platforms, and translates these shaders to the host platform's native language (HLSL, GLSL, and even GLSL ES).
 * For debugging purposes, it is useful to be able to examine the shader after translation.
 * 
 * This extension addes a new function to query the translated shader source, and adds a new enum for GetShaderiv's <pname> parameter to query the
 * translated shader source length.
 * 
 * Requires {@link GLES20 GLES 2.0}.
