gl.PopMatrix()
gl.PopMatrix() pops the current matrix stack, replacing the current matrix with the one below it on the stack.
Initially, each of the stacks contains one matrix, an identity matrix.
It is an error to pop a matrix stack that contains only a single matrix. In that case, the error flag is set and no other change is made to GL state.
Please consult an OpenGL reference manual for more information.
#GL_STACK_UNDERFLOW is generated if gl.PopMatrix() is called while the current matrix stack contains only a single matrix.
#GL_INVALID_OPERATION is generated if gl.PopMatrix() is executed between the execution of gl.Begin() and the corresponding execution of gl.End().
