a575c1c710 OpenGL2: Fix still projecting sun shadows onto nothing 
Increase the range for clamping the screen shadow depth to 1.0 (nothing
drawn). Old epsilon ~0.00000006, new 0.001. This fixes it on another
computer.

4c19ff2b55 OpenGL2: Don't project sun shadows onto nothing 
Don't project sun shadows (r_forceSun 1) on to view depth equal to 1.0
(nothing drawn or skybox). This caused a full second shadow of the
entire level in tr.screenShadowImage. It would move as the camera far
plane changed and rotate/stretch strangely as the camera view changed.

It was visible in-game on lightmapped transparent surfaces facing the
skybox and happen to overlap the extra shadow of the level.

This affected the glass in wop_padship's underwater room.
