as Ilmari pointed out in his letter some.. hmm.. time ago [1] Canvas spec
is missed method isPointInStroke(). It is _important_ thing as this
will be used for generating dynamic charts and graphs. For the moment,
selecting some point on a curve is not trivial problem...
(Although my real intention was to make simple graphics editor for
the web, but without isPointInStroke() it is impossible so far.)

In addition, i allow to use flash blend modes [2] in Canvas implementation 
for IE [3], so could it be added in specs too?
Also renamed globalCompositeOperation:
* lighter -> add
* darker -> subtract
* source-over -> normal
