On at least DC platform, the ShowStyleType enum is fit to a 4-bit
data size, so the 16-bit input value needs to be checked for
validity *before* it is cast to a 4-bit ShowStyleType.

Fixes some false warnings when games try to read in non-patch
files with names that start with A/B/S/T.

Phant1, PQ:SWAT, GK2, and Phant2 all have different audio maps
and audio volumes on each CD. In order to make this work within
ScummVM, where CDs are never swapped, each RESOURCE.AUD for these
games must be renamed to RESAUD.00x and each RESOURCE.SFX renamed
to RESSFX.00x.

Torin renders pics that are wider than 1024px; SCI3 bumps the
maximum line width to 4k.

This may come back in the future to deduplicate some gfx code,
but SCI32 had two different inlined ways of doing coordinate
conversions with different rounding methods, so CoordAdjuster32
didn't get used when the graphics system was rewritten.
At the moment, SCI32 code uses the mulru/mulinc methods from
helper.h for scaling up/down coordinates.

Fixes (at least) the native SCI save dialogs.

KQ7 2.00b, PQ:SWAT, Phant1, GK2, and Torin are all verified as
using the 'ignore' variant; SQ6 and QFG4CD are verified as using
the 'fail' variant. MGDX and Shivers could not be checked as they
have only Phar Lap Win16 executables, so took a guess based on
their release dates.

Drawing the cursor in this mode will result in a read overflow as
it is 8bpp.

Only cursor remains to be updated to go through GfxFrameout, and
then we can let GfxScreen go back to being SCI16-only.

We originally used hardcoded gameIDs and checked for CD-version.
Now the game option itself is checked for.
When it's available for the currently detected game, the option
is read, otherwise it defaults to false (same behavior as before).

When objects are added to a SegmentObjTable, it may cause the
internal storage for the table to expand and move to a new
region of memory. When this happens, all pointers to objects held
by a SegmentObjTable of the same type would be invalidated, due
to an implementation detail that should not be exposed. To prevent
this, objects are now allocated separately on the heap, so even if
the table's storage moves due to insertions, the objects owned by
the table will not, so references remain valid for the lifetime of
the object.

Pseudo mouse was functionality in SCI1+ games, that allowed the
user to control the mouse via keyboard cursor keys.
This new class only worked, when a tiny difference inside
the keyboard driver happened on kMapKeyToDir calls. We previously
tried to enable this behavior depending on cursor type, but
this didn't work correctly (Larry 5 for example was not detected
as such, but had PseudoMouse support).

This happens in e.g. Phant1, when walking from dining, to
reception, to up the stairs.

There is still a problem where the background is white instead
of black; this is caused by the palette of the video using entry
0 as white. This seems to have worked out OK in SSCI because the
video was not actually played back inside the engine itself, so
didn't interfere with the palette of the engine. ScummVM has no
such separation, so the palette of the video interferes with the
palette of the blank background pic, turning it white.

SCI32: Support Torin's autosave system
|
|
|
|
doCatalog::mode does not exist, the method is actually
doCatalog::changeState
This issue has been in there since the workaround was added
through commit 20b1d80d598e6f741e28c9a85d186e463d111816
