This commit implements all of the known plane transitions from
SCI2 through SCI2.1mid games. Because kSetShowStyle is always
called indirectly via the Styler game script, it is difficult to
find all the places where transitions are used. As such,
transitions that appeared to never be used have been added as
stubs which will trigger a game crash with a message to report
what was being done, so any missed transition types can be
identified quickly and then implemented.

Remap would crash SCI2.1early games with 19 remap slots, and
did not actually work in most cases in SCI2.1mid+ games.
The SCI16 implementation was moved to its own separate file but
was otherwise touched as little as possible, so may still have
similar problems to the SCI32 code.
1. Split SCI16 and SCI32 code into separate files
2. Use -32 prefixes for SCI32 code and no prefix for SCI16 code,
where possible, to match other existing code
3. Avoid accidental corruption of values from the VM that may be
valid when signed or larger than 8 bits
4. Added documentation
5. Add missing remap CelObj calls
6. Inline where possible in performance-critical code paths
7. Fix bad `matchColor` function, and move it from GfxPalette to
GfxRemap32 since it is only used by GfxRemap32
8. Fix bad capitalisation in getCycleMap
9. Remove unnecessary initialisation of SingleRemaps
10. Update architecture to more closely mirror how SSCI worked
11. Clarify the purpose of each type of remap type (and
associated variable names)
12. Split large `apply` function into smaller units
13. Fix buffer overrun when loading a SCI2.1early game with remap
14. Remove use of `#define` constants
15. Warn instead of crashing with an error on invalid input (to
match SSCI more closely)
16. Change the collision avoidance mechanism between the RemapType
enum and remap kernel functions
17. Add save/load function

This kernel call seems only to be used by KQ7 1.51 (which was
Windows-only) to send warnings to the user.
It was easy enough to do a basic implementation in the ScummVM
GUI rather than just make it an empty call, so now it is a thing.

These should be all the actually used subfunctions.

This line drawing code lives in a remodelled GfxPaint32 class
that is totally separate from GfxPaint16.

Replaces unused kernel calls to use kEmpty, and set correct
signatures for SCI32 kernel calls.

This provides a complete implementation of kDoAudio through
SCI2.1mid, plus partial implementation of SCI3 features.
Digital audio calls shunted through kDoSound have also been
updated to go through the SCI32 audio mixer, though these shunts
are a bit hacky because the ScummVM implementation of kDoSound
does not currently match how SSCI kDoSound is designed.
It is probably possible in the future to just replace the SCI1.1
audio code (audio.cpp) with the new SCI32 code, since the major
differences seem to be that (1) SCI1.1 only supported one digital
audio playback channel (this is configurable already), (2) it
had extra commands for CD audio playback and queued sample
playback.

The control panel initialisation script makes an invalid two-argument
call to get the width of the settings dial; this only happens to work
because the third argument on the stack was set to zero by an earlier
call.

The SCI16 versions do not implement the scaling algorithm used
by SCI32 so would be off by one in some cases.
|
|
applyRemap() is still not finished, so nothing is actually visible yet

Not all SCI2.1late/SCI3 function signatures are fully known yet,
but all subops are now represented in the kernel tables.
|
|
|
|
Replacing a valid signature error by a warning isn't useful.

This implementation is not 100% engine accurate, but it is
more accurate than what was there, and hopefully the differences
between this and the engine code are merely cosmetic.
The known (intentional) differences are:
1. Uses ScummVM rects inside the engine code, converting to/from
SCI rects on the kernel edges and when scaling
2. Fewer side effects when performing operations that *should*
have been pure from the start (like text dimension calculation).
Still not side-effect-free, but at least things like colours
and alignment do not need to be reset every time a measurement
is taken, unlike in the actual engine.
Editor controls and some other kBitmap code are temporarily
disabled as a result of changes to GfxText32 until they can be
updated to be engine-accurate.

kSetFontRes didn't exist in SCI2, showed up in SCI2.1early,
then was replaced with kFont subop 1 in SCI2.1mid.
|
|
This at least prevents SQ6 from crashing when going into the
introduction
|
|
Signatures in subops table are correct for length but unknown
types are marked as . instead of the correct type.

Thanks to lskovlun for his help
|

Added a TODO for rhis, for now
|
|
This also fixes kPalCycle signatures to be more accurate.

SIG_UNTIL_SCI21MID did not account for SCI2 games. Fixes GK1 DOS

- Detection works via signatures (couldn't find a better way)
- new kString subcalls were introduced SCI2.1 LATE
- kString now has signatures and is split via subcall table
- kString fix, so that KQ7 doesn't crash, when starting a chapter
- Sci2StringFunctionType removed, because no longer needed
|

The playBed option is not handled yet, only stored. This increases
the savegame format version.

Since the reference will be invalidated anyway by kUnload itself,
there's no real reason to check for its validity. We do the same with
kGraph() and kDisplay().

Apparently, the original does the same. Fixes bug #6535

In several SCI0 games, the parameter to kDoSoundFade can be null.
We handle that case, instead of adding individual workarounds per game
