/*
Функция для одновременной подсветки ссылок с одинаковым href,
на вход принимает:
1) selector — джеквери-селектор ссылок, чтобы
была возможность включить дублирующую подсветку в определённом фрагменте;
2) hoverClass — какой класс добавить по ховеру и псевдо-ховеру.

Инициализация для всего документа:
doubleHover('a', 'hover');

The Liang-Barsky algorithm is a cheap way to find the intersection points between a line segment and an axis-aligned rectangle. It's a simple algorithm, but the resources I was pointed to didn't have particularly good explanations, so I tried to write a better one.

Consider a rectangle defined by x_min ≤ x ≤ x_max and y_min ≤ y ≤ y_max, and a line segment from (x_0, y_0) to (x_0 + Δ_x, y_0 + Δ_y). We'll be assuming at least one of Δ_x and Δ_y is nonzero.

(I'm working with Flash, so I'll be using the convention that y increases as you go down.)

We want to distinguish between the following cases:

Dear C++ library writer,

1. If your library forces me to use new all over, I will hate you.

2. If your library has types with bogus values, I will hate you.

3. If the documentation for your library gets the terminology of its own domain wrong, I will hate you.

4. If I say "My God, it's full of stars!" when I see the function signatures in your library, I will hate you.
