22 * This is a special DisplayRegion wrapper that actually includes a pair of
23 * DisplayRegions internally: the left and right eyes. The DisplayRegion
24 * represented here does not have a physical association with the window, but
25 * it pretends it does. Instead, it maintains a pointer to the left and right
26 * DisplayRegions separately.
27 *
28 * Operations on the StereoDisplayRegion object affect both left and right
29 * eyes together. To access the left or right eyes independently, use
30 * get_left_eye() and get_right_eye().
