[CSS Shapes] Add BoxShape and FloatRoundingRect classes

[Hans Muller]

Currently the internal FloatRoundedRect class (see RectangleShape.h) supports two corner radii, which was sufficient for earlier version of the CSS Shapes spec. The current spec (http://dev.w3.org/csswg/css-shapes/) requires elliptical corners, two radii per corner.

[Hans Muller]

A BoxShape class would represent margin-box, border-box, padding-box, and content-box values, see http://dev.w3.org/csswg/css-shapes/#typedef-box.  

A float analog of RoundedRect is needed to represent a BoxShape's shape-margin and shape-padding bounds. A FloatRoundedRect is a rounded rectangle with four elliptical corners, each with its own pair of radii.

Added the BoxShape class. It's now used to represent shape-outside box values: [margin/border/padding/content]-box. BoxShape depends on a new FloatRoundedRect class, which is a float analog of the existing (int) RoundedRect class.

Updated the ChangeLog entry:

Added the BoxShape class. It's now used to represent shape-outside box values: [margin/border/padding/content]-box. BoxShape depends on a new FloatRoundedRect class, which is a float analog of the existing (int) RoundedRect class. The FloatRoundedRect class contains the same basic methods and accessors as BorderRect and adds a set of four methods, for example topLeftCorner(), that return a FloatRect that represents the bounds of one elliptical corner. I also added a method, xInterceptsAtY() that returns two X coordinates of the intersection between a horizontal line and the rounded rectangle.
