-Flot plugin for plotting images, e.g. useful for putting ticks on a
-prerendered complex visualization.
-
-The data syntax is [[image, x1, y1, x2, y2], ...] where (x1, y1) and
-(x2, y2) are where you intend the two opposite corners of the image to
-end up in the plot. Image must be a fully loaded Javascript image (you
-can make one with new Image()). If the image is not complete, it's
-skipped when plotting.
-
-There are two helpers included for retrieving images. The easiest work
-the way that you put in URLs instead of images in the data (like
-["myimage.png", 0, 0, 10, 10]), then call $.plot.image.loadData(data,
-options, callback) where data and options are the same as you pass in
-to $.plot. This loads the images, replaces the URLs in the data with
-the corresponding images and calls "callback" when all images are
-loaded (or failed loading). In the callback, you can then call $.plot
-with the data set. See the included example.
-
-A more low-level helper, $.plot.image.load(urls, callback) is also
-included. Given a list of URLs, it calls callback with an object
-mapping from URL to Image object when all images are loaded or have
-failed loading.
-
-Options for the plugin are
-
-  series: {
-      images: {
-          show: boolean
-          anchor: "corner" or "center"
-          alpha: [0,1]
-      }
-  }
-
-which can be specified for a specific series
-
-  $.plot($("#placeholder"), [{ data: [ ... ], images: { ... } ])
-
-Note that because the data format is different from usual data points,
-you can't use images with anything else in a specific data series.
-
-Setting "anchor" to "center" causes the pixels in the image to be
-anchored at the corner pixel centers inside of at the pixel corners,
-effectively letting half a pixel stick out to each side in the plot.
-
-
-A possible future direction could be support for tiling for large
-images (like Google Maps).
