Weston client compatability

[crondog]

So while working on touch, I came across some issues when running some weston client applications. I realise that there are missing features in wlc which could affect this but I just want to share what I have found as I might be important later. Some of these issues affect orbment and sway differently so it could be issues in that code too.

Flowers

• Left click does not change the flower. The code path of a left click in flowers.c ends up calling xdg_surface_move and doesn't end up doing anything
• Moving focus in/out of the view in sway causes the flowers.c resize handler to trigger. Which then causes a redraw so the flower changes. In orbment this does not happen
