I feel configure events and requests are messed up

[Bill Spitzak]

In Wayland the client allocates the buffer, not the compositor.

I think this is what is leading to the confusion here. The compositor 
has no say over how big the buffer is. Instead the client controls it 
and tells the compositor what the resulting size is.

To cause futher confusion there is an assumption that the compositor 
will then map this entire buffer onto the screen as a window, thus 
leading to worry that the client can force the screen to be obscured, 
and that it can ignore compositor resizing limits, etc. This is not 
true, the compositor can do anything it wants with the buffer, it is in 
effect a texture map that it can place part/all of onto the surfaces it 
composites onto the screen.
