Re: definition of "fixed spatial layout

There are very few spatial layouts that are necessary. Images with labeled
points are one (in or out of the canvas). Data tables are necessary without
a conversion to a relational equivalent.

Application layout is definitely not necessary for many applications. Take
Microsoft Word for example. The ribbon across the top can be useful, but
the space it takes is very intrusive. I prefer a linear presentation over
time. So I close ribbons until needed.

There is no reason why the boxes on a ribbon cannot expand to full screen
with 400% mag. Many app developers just don't provide this capability.
Namely, the ability to address panes and windows. I use an IDE that is
inaccessible to blind users because it lets me view my panes in full screen
mode.

The difference in informational content linearization and application
linearization is the dimension of linearization. Informational content is
linearized by space as in responsive design and supported by SC 1.3.2.
Application linearization is a temporal operation. It gives the ability to
view each main content area, pane, panel and panel box as a full screen
single purpose page, and the ability to navigate between them as you do a
job over time.
