The implementation of the tag tree did not
set the correct reset value for the encoder.
This lead to inefficent tag tree being encoded.
This patch fixes the implementation of the
ff_tag_tree_zero() function.

The log2_chroma_wh is derived from the sample separations of the
codestream if the file is a j2k codestream. Not sure if sample
separation is same is subsampling and whether using sample
separation values from the codestream to determine pixel format.

libopenjpeg2000 uses ceiling division while dividing tile
co-ordinates with the sample separation. Also, corrections
were made to the WRITE_FRAME macro.

This patch removes a check which throws an error if
the log2 precinct width/height is 0. The standard allows

This is with reference to my previous email on the mailing list
with subject: "query on pixel formats".
I wish to cleanup some errors in the decoder code. These changes
would allow the samples p1_01.j2k and p1_07.j2k to be decoded.
However, I am facing issues with pixel
From: Gautam Ramakrishnan
This patch makes selection of pix_fmt similar to
that in the native decoder. This makes samples such
as p0_05.j2k and p1_03.j2k decodable by libopenjpeg.
