Using the players's cursectnum instead of "updating" the sectnum means that it
won't glitch on SoS. The z clamping (basically a port of some code from
G_DrawRooms) is so that the view won't be drawn from under the floor when shrunk.

When shrunk, the player position is below the floor for some weird reason.
Updatesectorz would set the sector to -1, and the view would not be drawn.
