SCI/TODO

The following list is taken from Max's mails to -devel:

• Fixing all warnings
• Rearranging the files under engines/sci: I.e. get rid of include/ subdir (just move its contents to engines/sci, at some point at least)
• Converting stuff from "C pseudo classes" to real classes
• Replacing various generic FreeSCI stuff by their ScummVM counterparts. E.g. don't bother to rewrite engines/sci/include/int_hashmap.h -- instead change code to use a HashMap<int, ...> etc.
• In fact: Do use File, SearchManager, FSNode etc. instead of paths, fopen, etc.
• Don't use fstat
• const correctness in engines/sci/engine/savegame.c (this is a generated file, so change the source or generator, whatever is necessary)
• change the many nice existing function documentation comments to use doxygen syntax
• Turn code into templates in following files (now they generate code via #defines):
  • gfx/gfx_pixmap_scale.cpp
  • gfx/gfx_line.cpp
  • gfx/gfx_crossblit.cpp
  • gfx/resource/sci_picfill.cpp
  • gfx/resource/sci_picfill_aux.cpp
• Check old FreeSCI-scummvm branch / repos by Jordi for change that could be salvaged, e.g. the files sfx/device/scumm-midi.cpp and sfx/softseq/scumm-adlib.cpp, or the modifications to the SCI debugger to use the ScummVM console, and stuff.
• Replace the SCI sound mixer by Audio::Mixer
• Move everything into namespace SCI
• change #define lists into enums
• make the SCI tools compilable (to avoid bitrot, while we change code that they depend on), and finally usable again.
