more walls & wall changes

    1. gravity wall should not disable gravity in its zone, but create a "bubble" that is independent of the outside.

    2. pressure containment wall: pressure can;t go throught but particles can

    3. just a sum up of why we can;t have 1 pixel walls

    4. 1 way walls

    1. This would break saves, but could be implemented with another element/wall. (see other threads)

    2. Use TTAN with gaps in it. (It still blocks pressure within a radius)

    3. A Legitimate question. The best answer I can come up with is it's too hard to code. Even TTAN was built with a radius.

    4. Put portals on either side of WALL. Profit

    3. walls are 4X4 because every force grid is: pressure, velocity, (not sure about) newtonian gravity. Thats why strong bombs cause pixelated pressure displays. If TPT were to calculate pressure for single pixels, it would take 4X4 times as long (if the algorithm was left unchanged).

    (1) Wall width is controlled by the same variable that controlls pressure. (CELL)
    (2) It'll be laggy
    (3) Pressure calculations are good with CELL being 4
    (4) It'll be laggy
    (5) Every save (More than a million and counting) will break
    (5) It'll be laggy

    Yes vx and vy are 4x4, also it would probably be more like 16x as laggy.

    put portals next to block wall
