Single File Data Mapper Authentication for Sinatra
# NAME: authinabox
# VERSION: 1.01 (Dec 27, 2008)
# AUTHOR: Peter Cooper [ http://www.rubyinside.com/ github:peterc twitter:peterc ]
# DESCRIPTION: An "all in one" Sinatra library containing a User model and authentication
# system for both session-based logins OR HTTP Basic auth (for APIs, etc).
# This is an "all in one" system so you will probably need to heavily tailor
# it to your own ideas, but it will work "out of the box" as-is.
# COMPATIBILITY: - Tested on 0.3.2 AND the latest rtomayko Hoboken build! (recommended for the latter though)
# - NEEDS DataMapper!
# - Less work needed if you use initializer library -- http://gist.github.com/40238

Drawing an arrow in JS can be hard!
function drawArrow(x, y, w, h, rot) {
ctx.save();
ctx.translate((x + w / 2), (y + h / 2));
ctx.rotate(rot);
ctx.translate(-(x + w / 2), -(y + h / 2));
ctx.translate(x, y);
a = 0;
