* implemented single image screens
* implemented skeleton of the image scroller
* added RR-specific definitions to the menus (need to copy and adjust d_menu.cpp)
* added definitions for credits screens.
Not tested yet!
* Added a JSON-based header to the savegames so that the unified menu can read from a common data source.
* moved loading and saving of frontend independent data to the wrapper so that support is automatic.
- draw fullscreen blends below the console.
- moved all mouse event processing out of the SDL backend to D_PostEvent.
- removed all remaining code for dealing with mouse buttons directly.
Not only is this a deprecated feature - it also does not work right when complex lighting is at play, it must be done in the shader to get proper results.
This broke the savegame reader which still assumed it was working on compressed data. Everything will now take the uncompressed path.
In-stream optional compression is not a good idea anyway, this can and should be done better.
Also: Why is the savegame format architecture dependent???
* moved the binding commands to osd.cpp. They were in the global namespace already and this way everything to be tossed out is in the same place when the time comes.
* removed support for the OSDs native CVARs. The only ones left were some internal ones I won't need until this code can be replaced.
* same for the custpmization code the games added. Duke Nukem was the only one anyway to have a decent font for it.
I think this shows a fundamental misunderstanding of what constexpr means, even when declared as such it requires a constant argument to be treated as a constant.
But since nearly all uses of this were not using constants, the compiler was emitting actual memory accesses to the array each time this was used.
- disabled the user maps menu because it is hopelessly dependent on functionality that cannot be fixed. Better wait until the menu refactor to do it right - it'd be a waste of time fixing the current menus.
* saving of demos and savegames no longer mindlessly writes to the mod directory. All such access is now being rerouted through the special paths interface so that the game data can reside in write protected locations.
* refactored all occurences of klistpath except fnlist_getnames.
* do not allow CON scripts to write to arbitrary files. This is a massive exploit and can be used to cause real damage if someone knows how to play this thing - it's far easier than people may think! It will now write any such data to a special section in the main config which is safe and cannot be manipulated to write to random locations on the hard drive.
- consolidated the 3 identical S_OpenAudio implementations. The replacement code is disabled for the time being because it needs a rewrite. The replacement logic is uses is a bit too volatile.
- removed the old GRP scan code.
