puresuri presentation system Puresuri is a new way to make presentations in Racket using picts. Unlike slideshow, it is based on a single logical canvas with operations for adding and removing elements. Many ideas from unstable/gui/ppict are used. Look at tests/example.rkt for an example. Run: raco puresuri tests/example.rkt Try changing example.rkt while this is running. TODO - separate location and composition in placers - implement 'slide' compatibility with slideshow - replace PDF generation via latex with what slideshow does (plus fixes) - make portals give you the pict of the slide so you can put it inside the current slide - make an overlay to show the mouse position coords for easily placing objects - make a library for virtual whiteboards (everything is pushed up/down as things are added with implicit use of commit! in the code)
