/*
* In the radial gradient problem we are given two circles (c₁,r₁) and
* (c₂,r₂) that define the gradient itself. Then, for any point p, we
* must compute the value(s) of t within [0.0, 1.0] representing the
* circle(s) that would color the point.
*
* There are potentially two values of t since the point p can be
* colored by both sides of the circle, (which happens whenever one
* circle is not entirely contained within the other).
*
* If we solve for a value of t that is outside of [0.0, 1.0] then we
* use the extend mode (NONE, REPEAT, REFLECT, or PAD) to map to a
* value within [0.0, 1.0].
*
* Here is an illustration of the problem:
*
* p₂
* p •
* • ╲
* · ╲r₂
* p₁ · ╲
* • θ╲
* ╲ ╌╌•
* ╲r₁ · c₂
* θ╲ ·
* ╌╌•
* c₁
*
* Given (c₁,r₁), (c₂,r₂) and p, we must find an angle θ such that two
* points p₁ and p₂ on the two circles are collinear with p. Then, the
* desired value of t is the ratio of the length of p₁p to the length
* of p₁p₂.
*
* So, we have six unknown values: (p₁x, p₁y), (p₂x, p₂y), θ and t.
* We can also write six equations that constrain the problem:
*
* Point p₁ is a distance r₁ from c₁ at an angle of θ:
*
* 1. p₁x = c₁x + r₁·cos θ
* 2. p₁y = c₁y + r₁·sin θ
*
* Point p₂ is a distance r₂ from c₂ at an angle of θ:
*
* 3. p₂x = c₂x + r2·cos θ
* 4. p₂y = c₂y + r2·sin θ
*
* Point p lies at a fraction t along the line segment p₁p₂:
*
* 5. px = t·p₂x + (1-t)·p₁x
* 6. py = t·p₂y + (1-t)·p₁y
*
* To solve, first subtitute 1-4 into 5 and 6:
*
* px = t·(c₂x + r₂·cos θ) + (1-t)·(c₁x + r₁·cos θ)
* py = t·(c₂y + r₂·sin θ) + (1-t)·(c₁y + r₁·sin θ)
*
* Then solve each for cos θ and sin θ expressed as a function of t:
*
* cos θ = (-(c₂x - c₁x)·t + (px - c₁x)) / ((r₂-r₁)·t + r₁)
* sin θ = (-(c₂y - c₁y)·t + (py - c₁y)) / ((r₂-r₁)·t + r₁)
*
* To simplify this a bit, we define new variables for several of the
* common terms as shown below:
*
* p₂
* p •
* • ╲
* · ┆ ╲r₂
* p₁ · ┆ ╲
* • pdy┆ ╲
* ╲ ┆ •c₂
* ╲r₁ ┆ · ┆
* ╲ ·┆ ┆cdy
* •╌╌╌╌┴╌╌╌╌╌╌╌┘
* c₁ pdx cdx
*
* cdx = (c₂x - c₁x)
* cdy = (c₂y - c₁y)
* dr = r₂-r₁
* pdx = px - c₁x
* pdy = py - c₁y
*
* Note that cdx, cdy, and dr do not depend on point p at all, so can
* be pre-computed for the entire gradient. The simplifed equations
* are now:
*
* cos θ = (-cdx·t + pdx) / (dr·t + r₁)
* sin θ = (-cdy·t + pdy) / (dr·t + r₁)
*
* Finally, to get a single function of t and eliminate the last
* unknown θ, we use the identity sin²θ + cos²θ = 1. First, square
* each equation, (we knew a quadratic was coming since it must be
* possible to obtain two solutions in some cases):
*
* cos²θ = (cdx²t² - 2·cdx·pdx·t + pdx²) / (dr²·t² + 2·r₁·dr·t + r₁²)
* sin²θ = (cdy²t² - 2·cdy·pdy·t + pdy²) / (dr²·t² + 2·r₁·dr·t + r₁²)
*
* Then add both together, set the result equal to 1, and express as a
* standard quadratic equation in t of the form At² + Bt + C = 0
*
* (cdx² + cdy² - dr²)·t² - 2·(cdx·pdx + cdy·pdy + r₁·dr)·t + (pdx² + pdy² - r₁²) = 0
*
* In other words:
*
* A = cdx² + cdy² - dr²
* B = -2·(pdx·cdx + pdy·cdy + r₁·dr)
* C = pdx² + pdy² - r₁²
*
* And again, notice that A does not depend on p, so can be
* precomputed. From here we just use the quadratic formula to solve
* for t:
*
* t = (-2·B ± ⎷(B² - 4·A·C)) / 2·A
