[eclipse-pmc] PMC bug fix request: to allow printing on the mac

[Felipe Heidrich <Felipe_Heidrich@xxxxxxxxxx>]

GOALS/BENEFITS:

Due to a bug fix for DPI, printing on the Macintosh fails completely with
a NullPointerException when creating a Printer. There are further issues 
in
that some printer drivers do not report DPI. This causes division by zero. 

Printing worked in 3.3, but the DPI was always 72x72.

We propose that we put back exactly the same code as 3.3, with only java 
doc
changes to the file. We will reopen the original DPI bug and not attempt a
fix for 3.4.

ASSOCIATED BUGS:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=236419 (the null pointer)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=219133 (the dpi bug)

RISKS:
Very low. We are putting back code that was tested for 3.3. 

PERFORMANCE IMPACT:
None.
