Now that we no longer have a buffer border, we can render directly to
the video memory if the output surface is 8-bit and double buffering is
enabled.
Also adds a flag to force this even when double buffering is disabled,
because some systems emulate 8-bit mode with something else, so the
output is always buffered.
This required a tweak to the cursor to make sure that we clear it after
`SDL_Flip`.
This should gradually replace all the direct rendering of game texts
throughout the code. The interface is made to closly mirror that of the
art fonts as that is what will eventually be used for rendering Unicode
fonts both in the menus and ingame.
fixup! ✨ Generic game text render function
Uses integer math only: This speeds up the rendering and eliminates some
zoom artifacts.
Improves player indicator look -- it's now symmetric and more legible.
Rename the config entry for changing the quick messages texts
Other small improvements and simplifications
Set the quick spell hotkey text to be white with a black shadow
Add QuitGame action, unbound by default
Set the ItemInfo and QuestDebug keys to be unbound by default
Previously, we always loaded entire videos in memory before playing them.
`libsmacker` does not provide a streaming API but it does provide a
`FILE *` file pointer API.
We now take advantage of the `FILE *` API by streaming the videos on
platforms that support `fopencookie`.
This means faster startup and less memory usage on these platforms.
This option completely disables all audio handling, including audio
loading code and dependencies.
Dialog text length is estimated to be somewhere between
Cain and Griswold speed.
SDL_mixer can only stream a single music track
SDL_audiolib has unlimited streams.
With this change, we finally have streaming sounds (respecting
sfx_STREAM).
Audio options can now also be set via diablo.ini, which should help us
better diagnose the static noise issues.
Older Debian and derivatives come with sdl2-config.cmake file that does
not define any targets.
One such sdl2-config.cmake looks like this:
```cmake
set(prefix "/usr")
set(exec_prefix "${prefix}")
set(libdir "${prefix}/lib/x86_64-linux-gnu")
set(SDL2_PREFIX "/usr")
set(SDL2_EXEC_PREFIX "/usr")
set(SDL2_INCLUDE_DIRS "${prefix}/include/SDL2")
set(SDL2_LIBRARIES " -lSDL2")
string(STRIP "${SDL2_LIBRARIES}" SDL2_LIBRARIES)
```
Works around this by defining an `SDL2::SDL2` target ourselves.
