added the story so far to the journal as a way of clearning things in my head.
fixed calcbox() to use r,c coords and changed render to print out what it gets from normalize.
Still need to decide what render should do: just change r,c to x,y or to scale and then change.
removed reference to height and width from primitives.
added comment about r,c -> x,y conversion as i remembered it from before
Updated journal with last observations on story so far and added decisions from today.
All changes required to convert from the old x,y CS to the r,c CS within the core render pipeline are in this commit.
General changes:
  - made all the code in wordpic.js use only the bounding boxes and r,c CS.
  - calculated the overall bounding box of the picture using r,c CS
Specific changes:
1. converted all the placer & sizer functions to use r,c
2. converted normalize.calcBBox() and xlateToOrigin() to use r,c
3. converted the only primitive in wordpic.primitives to user r,c
Basic render pipeline working. There's a lot that's not working, but the basic place and size logic is in place.
Next step: get basic things like shape and fills to work.
added code to copy in any attrs from the input onto the shape. this allows id and fill style data to pass thru to the renderer.
Changes to get crisp lines. Seems to work.
Updated link to MDN from the wierd gsearch url to actual one.
Updated todos with tasks to get parse to work.
Initial integration of the ometa-js grammar that was in wp.ometa.
after some craziness (see journal in the ometa-js project for details), got standalone ometa to work in wordpic.
this required:
 - the libs to be copied over from my ometa-js fork
 - changes to wordpic-demo.html to accomodate ometa-js and our grammar inline.
 - minor fixes to ensure data is passed from textarea to ometajs correctly.
 - syntax changes to the demo picture so as to be understood by the parser.

Status:
 - the parser succeeds. However, the ret of the pipeline is expecting the otuput to be an AST; instead its the parse tree.

Next steps:
 - convert to AST asap.
