ScummVM engines are not built for synchronous screen locking (i.e.
updateScreen() can't be really used for any sort of blocking updates
otherwise performance suffers).
Single buffering now means deliberate tearing as a speed optimization
and triple buffering provides a tearingless picture with slight overhead.
The previous workaround was introduced to fix fighting using the keypad
in Indy 3. It enforced genering a number on KEYCODE_KP# events even
when KBD_NUM is not set. The issue on AmigaOS is that SDL never reports
KBD_NUM as being set. Instead we get different keycodes depending if
numlock is on or off (e.g. KEYCODE_KP3 and KEYCODE_PAGEDOWN).
The new workaround is to set the KBD_NUM modifier whenever we receive
a KEYCODE_KP# event from SDL. This way we also generate a number, but
in addition this is consistent with the modifier and works with code
that checks the KDB_NUM modifier (such as the GUI code or the AGI
engine).
Apple's desktop operating system was formerly called "Mac OS X" and "OS X", but since 2016 it has been called "macOS" (starting with version 10.12).
Changing across all comments and documentation to use this current terminology, except in cases where the historical versions are explicitly referenced. No code changes are made; we should consider changing those in future PRs.
Fixes GUI events leaking into engines at startup. This caused
Phantasmagoria 1 to skip its introduction if the game was started from
the ScummVM GUI with a keyboard (Enter) but not with a mouse because
the key-down event started the engine and the key-up event remained
in the queue.
This also purges and mouse events since we happen to already have a
purgeMouseEvents() method. We may want to also clear joystick inputs,
or possibly the entire event queue, but that can be done after the
upcoming release. For now, the known bug is fixed.
This config was handled in the DefaultEventManager, but this did not
work for engines that quit the game without using a QUIT_EVENT (such
as SCI). So now it is handled one level up directly in scummvm_main.
Note: It is still also handled in the DefaultEventManager so that we
get the correct confirmation dialog there when "confirm_exit" is true.
I reused the same flag that was already used for the same purpose
for the 'Confirm exit' dialog. This means that if we have both a
RTL and a Quit event in the queue, only the first one will have a
confirmation dialog. If this is an issue, we can instead introduce
a separate flag for the RTL dialog.
Different platforms have different levels of support of encodings and
often have slight variations. We already have tables for most encoding
with only CJK missing. Full transcoding inclusion allows us to get reliable
encoding results independently of platform. The biggest con is the need for
external tables encoding.dat.
It removes a duplicate table for korean in graphics/korfont.cpp
