Added an example to demonstrate canvas text.
Move canvas reuse up into the Canvas constructor.

This allows us to reuse the canvas elements without having to retain the
rest of the Canvas object, which should really be reset when the plot is
reconstructed.  It's also a little simpler, and the Canvas constructor
just feels like the right place for this code.
Only save references to old Canvas methods once.

Plugins are re-initialized with each re-plot (which may not be the right
thing to do, but that's how it works for now).  The previous approach of
saving references to the original Canvas functions therefore broke,
since the second time around we'd get a reference to our new function.
Instead we hold those references as globals within the plugin, and only
set them once.

This whole idea of replacing prototype functions is, now that I step
back and look at it, really awful.  This needs to be changed ASAP to
something less ridiculous.
Switch to semantic versioning.
Fix up URLs in the plugins.jquery.com manifest.
Axis and tick color options now make more sense.

The axis color now controls the color of the axis line, instead of its
ticks and labels, while the tickColor controls the tick color. This
makes a little more sense and provides the minor feature of being able
to change the axis line color separately from that of its ticks.  Pull
request #917 ought to be easier to merge now, too.
Update version number to 0.8.0-beta.
Ensure that axis lines align with their ticks.

Add an extra pixel to ensure that the lines cleanly join both top and
bottom ticks.  Also apply the sub-pixel offset only in the necessary
direction, so the lines don't start a pixel off from where they should.
Avoid an unnecessary intermediate variable.
Fix highlight and unhighlight inconsistency.

The unhighlight method retrieved the point differently from highlight,
and incorrectly.  It now matches the behavior of highlight.
Short-circuit when removing all highlights.

There's no need to continue in the function when all highlights are
being cleared.
Temporary patch for font-size parsing issue.

This partially addresses #991, but a more complete solution, or better
documentation, is still necessary.
Replace the stylesheet hack with inline styles.

The purpose of the stylesheet hack was to provide a default without
having to use inline styles on containers.  We can do this much more
neatly by instead just giving the inline styles to a parent container,
leaving users free to customize the children.
