Live-dumped from the capture client (Render::bw/bh 1024x720,
xinvscale/yinvscale 0.00025, tx 0.127875, ty 0.089875, vdst 0.1330767):
the replay context now uses retail unproject formula verbatim for the
ray caster and the exact frustum (fovY = 2*atan(ty/vdst), aspect =
tx/ty) for projection - no guessed camera constants remain.
foundry-deep conformance stays green.
