Extension of PPU rights for printing and scanning: cpdb-libs, cpdb-backend-cups, cpdb-backend-file

[Till Kamppeter]

Hi,

for those who only recently joined the DMB. I am leading the 
OpenPrinting project [1] [2] and for Ubuntu I have PPU rights for all 
printing- and scanning-related packages in Main and I am also MOTU.

With the introduction of the New Architecture for printing and scanning 
[3] into Ubuntu some re-structuring is happening in the printing stack 
in Ubuntu, which creates some new packages in Main.

After libppd (thanks for the approval) I need now PPU rights for the 
packages

- cpdb-libs
- cpdb-backend-cups
- cpdb-backend-file

Their MIRs got approved and the packages promoted an hour ago.

The packages implement the Common Print Dialog Backends [4] concept, 
where print dialogs of GUI applications do not talk directly to CUPS any 
more but communicate with print technologies like CUPS, cloud-printing 
services, or print-to-file by D-Bus with GUI-independent backends and 
the backends are developed and maintained by the same people who develop 
and maintain the print technology itself, OpenPrinting for the CUPS 
backend for example. This makes the print dialogs immediately working 
with changes, like now the New Architecture of CUPS and also allows 
providers of cloud printing services to make printing to their service 
available in all apps, as easy as printing to a local printers.

This way the print dialogs can easily cope with the New Architecture of 
printing.

Therefore I would like to ask you whether you could grant me PPU rights 
for these three source packages.

If any additional information is needed, please tell me.
