b5cb0b9f10 ref: gl: add r_dlight_virtual_radius. It potentially fixes ugly dlight cut off on largely scaled textures (or at least allows to tune it) 
It also adds a fix found in JoeQuake (which traces back to FitzQuake, in which
it is attributed to LadyHavoc, Darkplaces author) to exactly calculate whether
the light hits the surface, so we don't wrongly enable lighting on a surface by
an increased radius.
