[webkit-dev] Nesting a new CSS_SHAPES flag

[Dean Jackson]

Hi Floks!

We currently have flags for both CSS_SHAPES and CSS_EXCLUSIONS. In the former, shape-outside is nearly complete (thanks to hard work from Adobe contributors and others), but shape-inside is still waiting on a layout implementation, and is dependent on future specification work in CSS Exclusions.

In order to make it easy for ports to ship the bits that are stable (shape-outside) while disabling the bits that are not (shape-inside), I'm going to add a CSS_SHAPE_INSIDE flag. It will be dependent on CSS_SHAPES.
