A constant-time GLSL operation is an operation whose execution time does not vary based on the values of its operands. This extension will describe how a WebGL implementation can enforce this requirement.</p>
       <p>Additionally, this extension attempts to identify non-constant-time GLSL operations. All other GLSL operations are assumed to be constant time in both the WebGL implementation and the underlying GPU implementation. If this assumption is false on a particular implementation, then this extension must be disabled for that implementation. In the future, GPU vendors may be able to provide a mechanism to guarantee that the assumed GLSL operations are in fact constant-time.</p>
