Add a fix to the depth for the target texture

Browse source 
Fix to the named texture to have the 3d depth correctly rendered if a 3d view is inside the guiOffscreenCanvas.
It's disabled by default so it shouldn't change anything to projects that use guiOffscreenCanvas without the texture (like Oculus rendering).
