XSane tries to care about x-resolution, y-resolution and common
resolution options. When the backend tries to automaitcally set
y-resolution when x-resolution was changed this can interfere with the
xsane functions and it also is no good idea.

When the backend wants to make available a common resolution and
separate x- and y- resolution options then it should create three
resolutions options and on selection which of these are enabled:

resolution (range or list)
x-resolution (range or list)
y-resolution (range or list)
bind-resolution (boolean: enabled or disabled)

with bind-resolution enabled only resolution is enabled and defines
x- and y-resolution

with bind-resolution disabled only x-resolution and y-resolution is
enabled.
