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()
