Typically, the matrix mode is GL_PROJECTION, and (left, bottom, zNear) and (right,
top, zNear) specify the points on the near clipping plane that are mapped to the lower left
and upper right corners of the window, respectively, assuming that the eye is located at
(0, 0, 0). zFar specifies the location of the far clipping plane. Both zNear and zFar can be
either positive or negative.
Use glPushMatrix and glPopMatrix to save and restore the current matrix stack.
