Base.Graphics test suite

[chrisvoncsefalvay]

As it says on the tin ;) tests the following:

• Point/Vec2 identity
• Vec2 operations (+, -, *, /)
• rotate() for Vec2s
• norm()
• BoundingBox and its attributes
• BoundingBox ops: +, &, deform(), shift(), scale(), rotate(), with_aspect_ratio()
• isinside() testing

This is my first official Julia contrib. Enjoy ;)

can you squash into a single commit? Otherwise LGTM. thanks!

@chrisvoncsefalvay, if you don't know how to squash, it's like this:

git rebase -i origin/master
(now change "pick" to "squash" for the second two commits)
git push git@github.chrisvoncsefalvay/julia.git +cvcb-cov-gr

More detail http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html. That last command is a force-push, overwriting the history on this branch.

Then ping us when it's done, so we know it's ready to merge.

You'll also need to resolve a merge conflict. Please ask for help if you need it.
