This is GRC's cryptographically strong PRNG (pseudo-random number generator)
for JavaScript. It is driven by 1536 bits of entropy, stored in an array of
48, 32-bit JavaScript variables. Since many applications of this generator,
including ours with the "Off The Grid" Latin Square generator, may require
the deteriministic re-generation of a sequence of PRNs, this PRNG's initial
entropic state can be read and written as a static whole, and incrementally
evolved by pouring new source entropy into the generator's internal state.
----------------------------------------------------------------------------
ENDLESS THANKS are due Johannes Baagoe for his careful development of highly
robust JavaScript implementations of JS PRNGs. This work was based upon his
JavaScript "Alea" PRNG which is based upon the extremely robust Multiply-
With-Carry (MWC) PRNG invented by George Marsaglia. MWC Algorithm References:
http://www.GRC.com/otg/Marsaglia_PRNGs.pdf
http://www.GRC.com/otg/Marsaglia_MWC_Generators.pdf
----------------------------------------------------------------------------
The quality of this algorithm's pseudo-random numbers have been verified by
multiple independent researchers. It handily passes the fermilab.ch tests as
well as the "diehard" and "dieharder" test suites. For individuals wishing
to further verify the quality of this algorithm's pseudo-random numbers, a
256-megabyte file of this algorithm's output may be downloaded from GRC.com,
and a Microsoft Windows scripting host (WSH) version of this algorithm may be
downloaded and run from the Windows command prompt to generate unique files
of any size:
The Fermilab "ENT" tests: http://fourmilab.ch/random/

/**
* ALGORITHM:
* In an effort to keep things simple and working effectively, each dynamic node will resolve its
* collisions considering the rest of the world as static.
*
* Collision detecting will happen first. This can be considered a broad phase, but it is not especially
* efficient, as it does not need to be for this game engine. Every dynamic node is checked against every
* other node for collision area. If collision area is non-zero (meaning the current node sweeps into another),
* it is added to a list of hits.
*
* INITIALIZATION:
* - Physics constants are reset
* - Swept shapes are recalculated. If a node isn't moving, it is skipped.
*
* COLLISION DETECTION:
* - For a node, collision area will be calculated using the swept AABB of the node against every other AABB in a static state
* - These collisions will be sorted by area in descending order
*
* COLLISION RESOLUTION:
* - For each hit, time of collision is calculated using a swept line through the AABB of the static node expanded
* with minkowski sums (discretely, but the concept is there)
* - The collision is resolved based on the near time of the collision (from method of separated axes)
* - X is resolved by near x, Y by near y.
* - There is some fudging to allow for sliding along walls of separate colliders. Sorting by area also helps with this.
* - Corner to corner collisions are resolve to favor x-movement. This is in consideration of platformers, to give
* the player some help with jumps
*
* Pros:
* - Everything happens with a consistent time. There is a distinct before and after for each resolution.
* - No back-tracking needs to be done. Once we resolve a node, it is definitively resolved.
*
* Cons:
* - Nodes that are processed early have movement priority over other nodes. This can lead to some undesirable interactions.

/*
So as it turns out, WebGL has an issue with non-square quads.
It doesn't like when you don't have a 1-1 scale, and rotations are entirely messed up if this is not the case.
To solve this, I used the scale of the LARGEST dimension of the quad to make a square, then adjusted the vertex coordinates inside of that.
A diagram of the solution follows.
There is a bounding square for the quad with dimensions hxh (in this case, since height is the largest dimension).
The offset in the vertical direction is therefore 0.5, as it is normally.
However, the offset in the horizontal direction is not so straightforward, but isn't conceptually hard.
All we really have to do is a range change from [0, height/2] to [0, 0.5], where our value is t = width/2, and 0 <= t <= height/2.
So now we have our rect, in a space scaled with respect to the largest dimension.
Rotations work as you would expect, even for long rectangles.
