plagman 8250e5f3e8 Polymer: add preliminary support for sector masks. 
When walking the sectors in displayrooms, detect floor/sector masks to
place them in a mask queue. The queues are allocated on the heap, but
a stack pointer is maintained by the displayrooms to allow it to play
nice with mirror recursion.

Right now the masks are drawn after all of drawmasks is finished; that
means you can see sprites and wall masks through sector masks, but not
the opposite. There is a slight attempt at blending far to near, but
nothing too conclusive yet; that means that in some cases some sector
masks won't be visible through other sector masks, but it should work
for trivial cases.

The next step would be to copy all the drawmasks logic into Polymer
and have it (attempt to) properly interleave sector masks where they
belong in the blending order.

Raw Blame History

// here lies the GREAT JUSTICE RENDERER
// TODO :
// - CORE STUFF
// o there's also the texture alignment problem Hunter reported (san andreas fault)
// o RTT portals (water)
// o clip mirrors/portals to their planes
// o merge mirrors/portals from the same plane
// - SPRITES
// o sprite panning
// - SKIES
// o skyview
// - MDSPRITES
// o need full translation and rotation support from CON to attach to game world or tags
//
// the renderer should hopefully be pretty solid after all that
// the rest will be a bliss :)
