Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

| michael@0 | 16 | |
| michael@0 | 17 | SkTextBox is a helper class for drawing 1 or more lines of text |
| michael@0 | 18 | within a rectangle. The textbox is positioned and clipped by its Frame. |
| michael@0 | 19 | The Margin rectangle controls where the text is drawn relative to |
| michael@0 | 20 | the Frame. Line-breaks occur inside the Margin rectangle. |
| michael@0 | 21 | |
| michael@0 | 22 | Spacing is a linear equation used to compute the distance between lines |
| michael@0 | 23 | of text. Spacing consists of two scalars: mul and add, and the spacing |
| michael@0 | 24 | between lines is computed as: spacing = paint.getTextSize() * mul + add |
