cleaned up function interface to avoid referencing the file system in the worker functions.
replaced StringTable's operators with functions.. The main reason is that these are far easier to look up when browsing the source.
This also fixes a premature translation in SBARINFO that was done in the parsing stage, not the printing stage.
* making all members protected (but adding friend overrides for the classes which still need it)
* allowing to read data without retrieving the FResourceLump object.
* take I_BuildMIDIMenuList out of it
* pass the command line state to disable music from the init call.
* don't declare internal 'nomusic' variable in the header.
*Added Font and TextureID types to Option and Image Scroller items (List items already have these)
*Added "Class" instruction for Image Scrollers
*Added ability for Option items to read in their OptionMenuDescriptor (List and Image Scroller items already have this)
*Added "ForceList" instruction for Lists so that skill, playerclass, and episode menus don't get overridden
This is mainly for new games which have been designed for hardware rendering.
Note that this does not remove the software renderer's code - all it does is to disable the vid_rendermode CVAR by turning it into a static constant with the value 4.
* use a different subfolder for each IWAD's saves.
* do not allow load and save CCMDs to escape the save folder. Absolute paths and '..' are being blocked now.
* unified savegame path and filename generation in one single function. All ad-hoc file name generation was replaced.
* -loadgame will also use the designated savegame folder now.
- changed default value for midi_config to empty string since gus is not working with sf2 file
- fixed SetupDMXGUS not loading lump correctly, wrong use of CheckNumForFullName
- midi_config default to empty string, since lzdoom.sf2 doesn't seem supported (distorted sound)
- added absolute paths to FZipPatReader so we can add custom patches to resource files by using gus_patchdir and/or ULTRADIR variable (some custom maps has custom patches that can be added this way without putting them inside the resource file or in the same folder of the configuration file)
- set timidity_reverb_level min value to 0 in menudef.txt, set to 9 by mistake?
