/**
* Compares <code>left</code> and <code>right</code> componentwise. Returns <code>true</code>
* if they are within <code>epsilon</code> and <code>false</code> otherwise. The inputs
* <code>left</code> and <code>right</code> can be <code>float</code>s, <code>vec2</code>s,
* <code>vec3</code>s, or <code>vec4</code>s.
*
* @name czm_equalsEpsilon
* @glslFunction
*
* @param {} left The first vector.
* @param {} right The second vector.
* @param {float} epsilon The epsilon to use for equality testing.
* @returns {bool} <code>true</code> if the components are within <code>epsilon</code> and <code>false</code> otherwise.
*
* @example
* // GLSL declarations
* bool czm_equalsEpsilon(float left, float right, float epsilon);
* bool czm_equalsEpsilon(vec2 left, vec2 right, float epsilon);
* bool czm_equalsEpsilon(vec3 left, vec3 right, float epsilon);
* bool czm_equalsEpsilon(vec4 left, vec4 right, float epsilon);
