[css-shapes] issue 16716, shape from rendered content

Hey all,

This issue [1] captures the requirement that CSS Shapes allow wrapping
around the rendered contour of an element. This will be quite useful for
wrapping around text (and other renderings). My suggested resolution for
this issue is to move it to CSS Shapes level 2, along with the requirement
for using shapes from SVG elements that I've already moved out of the
current draft.

I'd like to restrict the first level of CSS Shapes to a small, extensible
feature. Adding more ways to define shapes should be easy to do in future
module levels. The most-frequently-requested method for defining a shape
is using the alpha channel of an image, which the first level includes.
Basic shapes allows for an approximation of other methods we can define in
the future, and matches their use in clip-path [2]. I think the current
draft has a useful subset of the possible shape definition methods, and we
should leave shapes from renderings for later.

Thanks,

Alan
