[Xournal-devel] Search almost there... thanks Alex!

[D M G. <dm...@uv...>]

Hi there,

Alex (who I think is in this list) took the pdf search code I
implemented and was able to get it to display. That was a great help,
because I had no idea how that needed to be done.

I looked at his code, and was trying to complete it, but discovered that
the model I had in mind when I started the search module was going to
fail. So I decided to restart again.

The current model is:

- a Page has a searchLayer (where the results are displayed). 

- It currently only makes sense in a document with a pdf background).

- By default it is empty,

- As one searches, this search layer highlights the results (and
  contains them as rectangles)

- An entire document is searched at once. This could be slow
  in long documents, but it is the cost of complexity--think evince that
  uses different threats to do it-- versus the simplicity of
  xournal. The current model, however, could allow to load "one" page at
  a time.
  
So far, we can:

* Find matches
* Attach the results to the search layer of the pages
* Display the results when the page is refreshed

It needs some work to get the details working:

* Refresh current page when matches found
* Fine tune user interface
* Remove current results before the new results are displayed
* Jump to next/previous match. 
* Highlight current match

If anybody is interested in hacking it:

Sorry Alex, for the huge diversion from your branch.
