Here is the caller graph for this function:

static CSSJanus::fixDirection ( $ css ) [static, private]

Replace direction: ltr; with direction: rtl; and vice versa.

The original implementation only does this inside body selectors and misses "body\n{\ndirection:ltr;\n}". This function does not have these problems.

See http://code.google.com/p/cssjanus/issues/detail?id=15 and TODO: URL

static CSSJanus::fixFourPartNotation ( $ css ) [static, private]

Swap the second and fourth parts in four-part notation rules like padding: 1px 2px 3px 4px;.

Unlike the original implementation, this function doesn't suffer from the bug where whitespace is not preserved when flipping four-part rules and four-part color rules with multiple whitespace characters between colors are not recognized. See http://code.google.com/p/cssjanus/issues/detail?id=16
