[openlp-dev] Loss of Renderer impact on Remote interface

Following a request from Simon H around the API's for the remote I started
looking at a set of changes and realized the new design for the
WenEngine may make the remote more difficult.

The current design is that the serviceitem contains an array of slides to
be displayed and this array has been processed so each slide fits a single
screen.  The current display builds an html page for the slide and displays
There are a number of different strategies for paging but they are managed
by the renderer.
This pattern allows the remote interface and the slide controller to easily
understand the number of slides even if some are split or all have the same

Moving towards the new pattern, if React were to provide this rendering
service how can the remotes know how many slides we have or how to
reference the React split slides.  As Raoul said yesterday this is work
outstanding but it would seem we need to understand how this will work as
it impacts a number of pieces of development.
