Re: Linux Weekly News quotes answer to Bruce's mail about Wayland

[Tim Dickson <dickson.tim@xxxxxxxxxxxxxx>]

I think based on the intransigence of wayland devs to add positional 
capability directly into the protocol, we would be left one of the 
following options.
1. create a new gambas "universal" compositor extension to provide the 
positioning capabilities, which would have to work with all current 
compositors,
2. create a gambas compositor that provides all the functionality that 
gambas and it's application developers want
3. Make XWayland a dep if your desktop is wayland based, and rely on the 
x-based  positional support.
4. create a gambas runner program which treats all gui programs as 
sub-programs of a full-screen window and has the capabilities of 
positioning them relative to itself, if that works?.

It certainly appears that wayland devs did not consider that programmers 
may want to develop widgets separate from a compositor. It's a wonder 
they got "buy-in" from qt and gtk. I'm surprised they didn't just add 
extra functionality to X to report screen usage. That would have been 
way easier and simpler and covered their examples of infotainment 
systems, bill boards, tablets, laptops and desktops. A simple info 
character or two per display would have done it, instead of inventing an 
entirely new but broken protocol.  (rant over)
