Refactoring app/disp_callbacks.c:ddisplay_canvas_event.c

["Andrew M. Botros" <andrew botros gmail com>]

I am currently working on refactoring app/disp_callbacks.c:ddisplay_canvas_event.c, I pulled most of the code out, I write just a few lines of new code to keep things working and tidy. I wonder if that's what you needed to be done. I also restructured some of the code in the same file, just tabs and stuff like that, and as I didn't find any coding guidelines for dia, I wonder if that might annoy anybody. And actually was thinking why don't we have coding guidelines for dia..?
It wasn't the easiest thing for me to find where the brace starts and ends...
