Okay I think perhaps I am completely failing to comprehend what is going on.
The client I am thinking of is not trying to do "partial pixels". What I
am thinking of is the most simple client you can imagine that knows what
the output_scale is and decides it wants to render images at full
resolution.
If for instance the output_scale is 3, then I think the client will set
the buffer_scale to 3, and then the pixels in the client's buffer will
map 1:1 to the pixels on the output device. There are no "partial pixels".
If this client wants a rectangle that is covered by an image produced by
this scaling extension, it appears to me that it cannot be any integer
number of buffer pixels. It can only be multiples of 3 pixels in both
size and position.
Please correct me if I am misunderstanding this, but I have read it over
and over and over and it sure looks like this is what the design does!

I realize this but I still have to express my complete dumbfoundment that
you think this is ok.
You're attempting to design for the problem space where clients create
configurations which cannot be displayed except by attempting to
invent the concept of 'partial pixels', where a buffer size of
79.3333... is not only meaningful but a design goal. The opposing
position is 'don't do that': clients should avoid getting themselves
into these situations in the first place.
Your proposals really come across as attempting to design for
situations which should never occur (and can't meaningfully be dealt
with by extant hardware), optimising for hugely misguided clients in a
fit of completism. That's your view, which you've made very clear,
but I don't think it's shared by anyone else in these threads.
Cheers,
Daniel
