- removed FS HUD pics. No mod in existence ever used them and a quickly thrown together test showed that the code did not even work. And since there's no reason to fix it they are gone now.

- some preparations for converting the player serialization code. - converted sound and canvas texture serialization. - refactored file_zip, so that it can be used to load loose zip files and extract their compressed data directly. - added handling to FSerializer to generate and consume compressed Zip file entries. If all goes well this will allow saving savegames as Zips when the rework is done, which will make analyzing them a lot easier.

- allow the compact and pretty writers for JSON to coexist by wrapping the whole stuff into another class that calls the proper one as needed. Due to the implementation it is not possible to decide at run time how this should behave so there have to be two different objects for either mode. - savegame code handles new format.

void ReadObjects(bool hubtravel);
- removed the sequential processing of JSON objects because the benefit is too small. After testing with a savegame on ZDCMP2 which is probably the largest map in existence, timing both methods resulted in a speed difference of less than 40 ms (70 vs 110 ms for reading all sectory, linedefs, sidedefs and objects). This compares to an overall restoration time, including reloading the level, precaching all textures and setting everything up, of approx. 1.2 s, meaning an increase of 3% of the entire reloading time. That's simply not worth all the negative side effects that may happen with a method that highly depends on proper code construction. On the other hand, using random access means that a savegame version change is only needed now when the semantics of a field change, but not if some get added or deleted. - do not I_Error out in the serializer unless caused by a programming error. It is better to let the serializer finish, collect all the errors and I_Error out when the game is known to be in a stable enough state to allow unwinding.

{
- some preparations for converting the player serialization code. - converted sound and canvas texture serialization. - refactored file_zip, so that it can be used to load loose zip files and extract their compressed data directly. - added handling to FSerializer to generate and consume compressed Zip file entries. If all goes well this will allow saving savegames as Zips when the rework is done, which will make analyzing them a lot easier.

return arc.Array(key, &style.BlendOp, def ? &def->BlendOp : nullptr, 4);
- removed FS HUD pics. No mod in existence ever used them and a quickly thrown together test showed that the code did not even work. And since there's no reason to fix it they are gone now.

- Fixed GCC/Clang regression post serialization.
