1. We were using the layout for the printer drop down from the
print dialog as the list item in the all printers activity.
This layout was not high enough. Now we have a separate
layout for the drop down and for the list. Note that they
are almost identical but this is better that writing java
code to lookup the height from the theme and change it
programatically since the java code is almost half the size
of the layout and leads to spreading the logic in both the
layout file and the java code.
2. The padding of the printers list was not correct. Now it
mimics the bahavior in settings where we change the padding
based on orientation.

1. The print dialog was resizable and as a result when printers
come and go its size changes which looks bad. The dialog is
now trying to be maximally large limited by a max size or the
screen - whichever is smaller. This required moving from
GridLayout to several LinearLayouts since the former does not
support distribution of empty space evently between the items
in a row. Also we want all items in a column of inputs to be
of equal size (the spinners specifically).
2. Added labeledBy attribute to associate a view with another one
that serves as its label for accessibility purposes. We have
lebelFor attribute but it is not useful in most layout files
since it has to refer the auto-generated id of a view which
usually appears later in the layout file, thus generating a
compilation error. This was needed for the accessibility support
of the print dialog.

2. Disabling the spinners or the print button did not produce
visual feedback leading to user frustration.

1. Added support for reporting the old print attributes during layout.
Now we keep track of the old print attributes, so the app can
compute the delta and decide whether re-layout work is needed.
2. Fixed PrintDocumentAdapter callback interleavings. Layout callbacks
were intermixing with write ones - a mess. Now we make an attempt
to cancel layout and write if they respond to cancellation, otherwise
we wait but do not interleave them.
3. Refactored the PrintJobConfigActivity for easier maintenance and
to have a single update UI method that does the minimal amount
of work.
