This was originally invented to fix the sprite offsets for the hardware renderer.
Changed it so that it doesn't override the original offsets but acts as a second set.
A new CVAR has been added to allow controlling the behavior per renderer.
This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
When running in a confined environment (such as a snap) it may not be
possible to write to directories such as ~/.config. By using the $HOME
variable instead of the '~' shortcut, the confined environment can pass
an alternative 'home' directory with write privelges.
I have only changed this for posix/unix and haven't touched code for
MacOS, as I don't know if that behaves differently
* do not use the global temp directory. Instead create one in the AppData folder.
* removed lots of unneeded code from tmpfileplus.
* use C++ strings in there.
Since this is a non-standard function it's better kept to as few places as possible, so now DirEntryExists returns an additional flag to say what type an entry is and is being used nearly everywhere where stat was used, excluding a few low level parts in the POSIX code.
- let FScanner::OpenFile return an error instead of throwing an exception. The exception was never used anyway aside from being caught right away to be ignored.
- now that the frame buffer stores its render time, the 'ms' return from I_GetTimeFrac is not needed anymore, we may just as well use the globally stored value instead.
The only feature this value was ever used for was texture warping.
* store the frame time in the current screen buffer from where all render code can access it.
* replace some uses of I_MSTime with I_FPSTime, because they should not use a per-frame timer. The only one left is the wipe code but even this doesn't look like it needs either a per-frame timer or a timer counting from the start of the playsim.
- moved timer definitions into their own header/source files. d_main is not the right place for this.
- removed some leftover cruft from the old timer code.
