New code for working with ePubs and XHTML

Hi Dan

I'm glad you're finding it useful. Unfortunately, this is still just some pieces of a project right now, and not a finished ePub reader application. There is a sort of spaghetti-code class in my app that hooks up the images and does all the styling. I haven't had time to refactor this into something generally useful yet. So, this explains the omission.

The images are all unzipped from the ePub and all have loaders that are indexed by url in the ePub's images Object. So, you only have to add something like this somewhere to hook up an img tag to the bitmap. Then you would also have to add some styling to make it show at the right dimension in the flow.

inlineGraphicElement.source = Bitmap( epub.images["/images/my_img.jpg"].loader.content );

The CSS is an unfortunate topic. At the time I was doing this, I determined there was no way to get the CSS styles applied to the flow "for free" using any of the existing means that I knew of. I feared it would be necessary to write my own engine, and I stopped before going there. I was interested in applying my own styles in the application, rather than those in the doc. So this code does not respect stylesheets at all yet.

I hope that there will be a better answer to this in the future.

The various ways of applying styling across TLF documents is something that should be explored more. I may be able to get a post together describing the approach I took. Also very interested in what others who are working on big documents have done.
