This removes the unnecessary Buffer subclass and stops most places
where the output buffer was being interrogated about dimensions
instead of GfxFrameout.
Convert macros and vars to enums, rename keyboard events in
preparation for adding key up events, clean up unnecessary nested
conditionals, add TODOs for potential future work.
This change invalidates earlier SCI32 save games, which separated
arrays and strings in an incompatible manner. Old save games
contain invalid references to a string segment which no longer
exists, and contain incompatible array structures that lack
critical type information.
Bitmaps in ScrollWindow and Robot code are managed by the kernel
and not by game scripts, although they must be able to be
referenced through a reg_t. To prevent incorrect GC of bitmaps
that are in use but not referenced by any game script, explicit
memory management of hunk entries can be enabled.
Controls that manage their own event loops and call frameOut
directly generally need to sleep in order to avoid 100% CPU,
just like the main VM event loop.
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.
Titled text bitmaps do not appear to be used by any game scripts.
They seem to only be used by the error manager in SSCI, but
ScummVM has its own error handling, so we don’t need this
implementation.
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.
Was the ScummVM-system-Keycode, sometimes modified.
Changed Menu/Portrait/Controls32-code to use .character instead.
Cleaned up a bit of code in getScummVMEvent()
