-- Needed to escape the scrolling div, which wasn't possible with
hint.css.
-- Couldn't switch everywhere, unfortunately, because
angular-ui-bootstrap tooltips have some nasty bugs dealing with disabled
input fields where the tooltips wouldn't go away.
-- Generating HTML with a doT.js template function; hopefully easier to
maintain.
-- More of the parameters refactored into the JS code, rather than
relying on being in the CSS; benefit => those parameters are available
when I do SVG rendering.
-- Also, now using Stylus to compile & minify CSS, and auto-inline small
images (Sublime project describes how to compile).
-- New color picker (angular-bootstrap-colorpicker)
-- Color picker placed beside each label field.
-- Can also drag & drop from palette to label fields (using
angular-dragdrop).
