b5420b8a9a LibGfx: Implement PNG filtering on write
Is it another great upgrade to our PNG encoder like in 9aafaec259?
Well, not really - it's not a 2x or 55x improvement like you saw there,
but still it saves something:

- a screenshot of a blank Serenity desktop dropped from about 45 KiB
  to 40 KiB.
- re-encoding NASA photo of the Earth to PNG again saves about 25%
  (16.5 MiB -> 12.3 MiB), compared to not using filters.
