WebGL2RenderingContext: uniformMatrix[234]x[234]fv() method

The WebGL2RenderingContext.uniformMatrix[234]x[234]fv() methods of the WebGL 2 API specify matrix values for uniform variables.

Note: There are no 2x2, 3x3, and 4x4 versions of this method. They are abbreviated in 2, 3, and 4, respectively. See the syntax below.
