Cogl.MatrixStack.prototype.rotate

function rotate(angle: Number(gfloat), x: Number(gfloat), y: Number(gfloat), z: Number(gfloat)): void {
    // Gjs wrapper for cogl_matrix_stack_rotate()
}
  

Multiplies the current matrix by one that rotates the around the axis-vector specified by x, y and z. The rotation follows the right-hand thumb rule so for example rotating by 10 degrees about the axis-vector (0, 0, 1) causes a small counter-clockwise rotation.
