water111 a918e2d9de [gfx] Clean up background renderer matrices, fix "hole covers" (#2866) 
The way we got/stored background matrices is a bit weird and full of
leftovers from the first attempts at porting renderers. This doesn't
work well with the Jak 2 "other camera" system where some stuff is
rendered with a different camera matrix.

This cleans most of it up. The exception is that the collide mesh
renderer and the additional sprite culling I added still need to peek at
some cached camera matrices.

This fixes the problem where etie uses the wrong matrices for "other
camera" levels. Now the "hole covers" go in the holes in the background
of the throne room.
