Handle STOR/FTCH the same way the RA1 game engine does:
On STOR, save the next following FOBJ (not the decoded image)
in a buffer; decode it on FTCH.
Used extensively by Rebel Assault 1 for e.g. the cockpit: A STOR-ed
codec21 object which only covers parts of the buffer is FTCHed
as last object in

- Various optimizations in the shade

This gets fftools its own management of log level and flags for and
provides an fftools-specific logging callback.
This makes it easier to implement specific logging behaviors which are

The size of the video frame (FOBJ) of the old codecs (ANIMv0/1/2) can
very reliably be determined:
- ANIMv0/1 (=Rebel Assault 1) uses a 384x242 internal buffer for
everything. The codec parameters only describe the size and offset
of the specific FOBJ on that buffer.
- ANIMv2 titles usually us
This patchset improves especially support for SMUSHv1 (Rebel Assault 1),
adds missing codecs and functions and improves reliability of SMUSHv1/v2.
#1 improves frame size detection.
#3 changes the left/top values to signed, as RA1 makes heavy use of
negative offsets.
#4 adds workarounds for RA1
This codec works on 4x4 pixel tiles, which can be generated and read
from the datastream. They're both identical, codec5 misses a tile
index to skip the current tile.
Codecs33/34 are the same as 4/5 but with a different tileset generator.
Used only in Rebel Assault 1.

This codec alternatingly skips and changes existing pixels.
A second 16bit parameter in the FOBJ header indicates how to do
the pixel changes: either by specifying a LUT in the codec datastream
or by adding a constant value to the pixel.

Fixes a lot of Rebel Assault 1 videos and Rebel Assault 2 space
scenes (e.g. 08PLAY.SAN which consists only of codec1/2/21 objects
which only ever touch parts of the buffer).
- for ANIMv1 (Rebel Assault 1): set palette index 0 to all
protocols like local socket and local file. In our product, I set
