The in-game menu contains not only subtitles and volume settings,
but also load and save game options. Every time the menu was opened
it would write the subtitles and audio volumes to the ConfMan
resulting in toggling on overriding global options for this game, which
was a but strange when it was previously using global options and we
only wanted to load a game. So now the settings are written to ConfMan
from the in-game menu only when they are actually changed.
The were defined as uint8 and the code was inconsistent in the
way they were handled, for example setting them to 1 in some
places and to true in others. It was working but relying on implicit
conversions both ways between 1 and true.
This transition style was used when exiting the asteroids minigame
in PQ4, though it appears likely that this was an error in the
original game script since it does not actually do anything in the
context that it is used (neither here nor in the original
interpreter).
Still, this code is already written, and it fixes the crash, so in
it goes.
Fixes Trac#9856.
1. Added a new game option for linear interpolation when scaling
overlay-mode video in ScummVM builds with USE_RGB_COLOR;
2. Implemented SCI2.1-variant of the VMD player renderer (fixes
Trac#9857), which bypasses the engine's normal rendering
pipeline;
3. Improved accuracy of the SCI3-variant of the VMD player by
writing HunkPalettes into the VMD's CelObjMem instead of
submitting palettes directly to GfxPalette32.
1. Added a new game option for linear interpolation when scaling
video in ScummVM builds with USE_RGB_COLOR;
2. 8bpp videos that put black in a palette index other than 0
(KQ7) should now always render correctly without the earlier
game-specific workarounds which did not work very well;
3. Data from game scripts regarding video size and position are
now ignored, since games always just try to show videos in the
middle of the screen, but frequently get this a little bit
wrong, causing either bad aspect ratios or off-center videos;
4. Builds without USE_RGB_COLOR support will not crash when
attempting to play >8bpp AVIs, like those from KQ7 2.00b.
Fixes Trac#9843, Trac#9762.
Destroying and recreating the SDL window whenever the video mode
changes in SDL2 is not necessary and causes several problems:
1. In windowed mode, the game window shifts position;
2. In fullscreen mode in macOS, every time the window is
recreated, it causes the OS to play its switch-to-fullscreen
animation again and emit system alert noises;
3. The window content flickers; and
4. The engine loses events from the old destroyed window.
This patch changes the SDL backend code to avoid destroying and
recreating the SDL window when using SDL2, except when switching
OpenGL modes, since there is no way to change the OpenGL feature
of a window.
There are still some outstanding issues with OpenGL where window
size ends up getting reset even though the user has resized it;
this will probably need to be addressed at some point in another
patch.
Thanks to @bgK and @criezy for their feedback which made this
patch much better.
