Gerbview: remove dependencies from Pcbnew.

Code cleaning (remove dead code, add comments).
Minor other enhancements.

-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe.
-It provides in-memory compression and decompression functions,
-including integrity checks of the uncompressed data.
-This version of the library supports only one compression method (deflation)
-but other algorithms will be added later
-and will have the same stream interface.
-.LP
-Compression can be done in a single step if the buffers are large enough
-(for example if an input file is mmap'ed),
-or can be done by repeated calls of the compression function.
-In the latter case,
-the application must provide more input and/or consume the output
-(providing more output space) before each call.
-.LP
-The library also supports reading and writing files in
-.IR gzip (1)
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-The library does not install any signal handler.
-The decoder checks the consistency of the compressed data,
-so the library should never crash even in case of corrupted input.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h .
-The distribution source includes examples of use of the library
-in the files
-.I example.c
-and
-.IR minigzip.c .
-.LP
-Changes to this version are documented in the file
-.I ChangeLog
-that accompanies the source,
-and are concerned primarily with bug fixes and portability enhancements.
