59e7f0597d pngparse: improve parsing of the image
Everytime a buffer is being provided from baseparse, we are parsing all the data from the beginning.
But since we would have already parsed some of the data in the previous iterations,
it doesnt make much sense to keep parsing the same everytime.
Hence skipping the data which is already read in previous iterations to improve the parsing performance.

6e3518dfd6 pngparse: optimise reading of png files
Read PNG data chunk in one go by letting the parser
base class know the size we need, so that it doesn't
drip-feed us small chunks of data (causing a lot of
reallocs and memcpy in the process) until we have
everything.

Improves parsing performance of very large PNG files
(65MB) from ~13 seconds to a couple of millisecs.

07ba033943 pngparse: Proxy upstream framerate on srcpad if avalaible
If the user sets it himself with capsfilter, the information should be
kept and transmitted downstream.
