As Vulkan crashes immediately on launch on a lot of Android devices (for around 15% of users that commented on the Android beta on Discord).
The previous usage of the OpenGL backend in the shortcuts was incorrect, as this backend is not strictly available on Android and the GLES backend should be used instead, as this is also what is displayed in the graphics settings.
The functions of the client component `CSounds` had a volume parameter which was unused. In some cases, the wrong value (`0`, presumably for the flags) was passed as the volume, which is now changed to `1.0f`. The player ground skid sound was previously set to play only at `0.25f` volume though this parameter was unused, which is also changed to `1.0f` to preserve the historic behavior.
A parameter is added to the engine sound play functions to directly set the volume without having to acquire the lock again.
Fix sound position not being respected for hook hit and ground jump sounds as the position parameter was ignored in the `CSounds::PlayAndRecord` function. Add TODOs for issues with this function for demo recording.
Parameters are ordered consistently and default parameter values are removed.
Duplicate code in the `CSounds` play functions is reduced by reusing the `PlaySample`/`PlaySampleAt` functions.
Fix incorrect panning value (`1.0f`) being set for GUI and Global sound channels after sound volume is changed, whereas the panning value is initialized to `0.0f`. Now the panning value is set to `0.0f` consistently. This should not have had any effect, as GUI and Global sounds do not have a position which would be affected by the panning value.
Show error messages when loading maps, when exporting images/sounds and when embedding images, if images/sounds could not be loaded. Images and sounds not being loaded is supported so the editor can be used to fix maps by removing/replacing the images/sounds.
Saving maps is prevented if embedded images/sounds could not be loaded, as the data is required to save the map.
Always convert image data to RGBA and dilate if enabled also for external images, as images may be embedded later and should therefore always be in RGBA format.
Add separate UI element IDs for the quick action buttons in the prompt dialog, to ensure that the UI element IDs are different from the IDs used for the regular menu buttons. Otherwise, some buttons could not be activated with clicks because the menu button with the same ID was rendered first.
Closes#8998.
The `sx` and `sy` parameters are unnecessary, as they are always set to zero.
The checks in the `SelectSprite` functions are changed to assertions, as passing a wrong sprite ID is a programming error.
