2365b678b3 IMAGE: Fix MSVC warnings 
Fixes warning C4067: unexpected tokens following preprocessor directive
due to non-standard "and" "or" operators

8ffa737901 IMAGE: Remove decoding JPEG directly to RGB565 
It's not supported by ancient versions of libjpeg-turbo, and there is no
way to detect if support is available without doing a compilation
test...

0f57aea2df COMMON: Use a prefix table to speed up the Huffman decoder 
Symbols for codes shorter than the prefix table index width are stored
in the table. All the entries in the table with an index starting with
the code are set to the symbol value. That way, when decoding it is
possible to get the number of bits corresponding to the table width from
the bitstream and directly find the symbol value. Longer code still need
to be searched for in the codes list.

b195ff5e19 GRAPHICS: Add support for PICT opcode $90 BitsRect 
Add limited support for unpacked PICT bits which FPFP Mac requires.

SCI games use packed PICT bits unless an image is less than 8 bytes
per row in which case they can't be packed, like FPFP's shovel icon.

Fixes bug #7059 which prevents the game from being completed.

d4f8b330d6 IMAGE: Honor nb_fields when calculating frame duration 
From what I understand, this has something to do with the image
being either made up from two or three parts. When it's made from
three parts, the frame should be displayed for half again as long
as normal.

This makes the speed of the Zork: Grand Inquisitor video look
about right to me. It's still out of sync, but it doesn't seem to
get *more* out of sync as the video progresses.

fc7fa1de3a VIDEO: Use liba52 to decode audio. This is still laughably broken 
At the moment, this produces nothing but misery in the form of
Valgrind warnings and horrible noise.

4702681be2 IMAGE: Explicitly initialize CinePak codebooks 
Starship Titanic produces lots of "uninitialized value" warnings
at the very beginning of the game, when turning right. This is
because in the very first movie frame it uses codebooks that have
not been loaded. Explicitly set their data to 0 to guarantee
consistent behavior.

194984de2f IMAGE: Remove unused end info structs from PNG code 
Thanks to @dafioram for noticing the problem & sending an initial
patch, and to @wjp for noticing further that the PNG reader did not
even use the end info struct it created either.

Fixes Trac#10217. Closes gh-1028.

dde259f068 COMMON: Remove BitStream base class to allow inlining calls 
All users of BitStream were in fact using a specific, hardcoded variant,
so we can hardcode that variant, removing the need for virtual calls,
and enabling inlining.
