As I described at Linaro Connect late-connected devices could cause new
constrains to appear. I.e. some (additonal) HDMI connection or WiFi Display etc.
Including all the might-happen devices might lead to unoptimal buffers
just to be able to handle some rarely-happen events.

I guess the easy resolve here is for the user to do a reallocation with
the new constraints added and replace the buffer(s) in question, but
with a slight lag in enabling the new device.
