Possible text-shadow enhancements

Hello everybody,

This is actually a follow-up to an old proposal written a few years ago:
http://lists.w3.org/Archives/Public/www-style/2008Oct/0266.html

In short, the proposal was to improve text-shadow in two simple ways:
- add an optional spread radius, to replace text-outline, and allow a
wider range of effects
- text-shadow could accept the foreground color, to avoid the
unreadable text issue in case the user agent does not support the
property (for graceful degradation):
  text-shadow: [fgColor,]? shadow [, shadow ... ];

I have written a simple mock-up of what is possible with the HTML5
canvas tag, as well as a few (basic) examples here:
