This implementation only reads GIF, BMP and PIC formats. No animated GIF support because stb_image does not handle that.
PNG, JPG and TGA are still being handled by the existing dedicated implementations.
PSD and HDR are impractical for reading texture data and thus are disabled.
PnM could be enabled, if its identification semantics were stronger. stb_image only checks the first two characters which simply would falsely identify several flats with the right colors in the first two bytes.
This is more or less a waste product of getting stb_image to work with something actually testable, so it is just provided as-is.
This is not useful by itself but can be used for adding new features later, e.g. mod-wide compatibility settings or file specific lump replacement or injection.
Many had leftover non-default constructors/ assignment operators, and some were initialized, even though the initialized data was never used.
In case of FCycler this even caused a default setting to be overwritten when used inside FDynamicLight.
Character classification is no longer affected by quirks of standard library implementation
Lookup table for own function was generated with Python thanks to Unicode Database module from its standard library
Explicitly set locale for POSIX targets was reverted to C

Added 5 xbrz_... CVARs to control various settings of upscaling process
Added xbrz_colorformat CVAR for buffered (zero) and unbuffered (any other value) color format
The first one requires a restart because settings are applied once to a precalculated buffer
The second one has reduced performance with ability to apply settings on-the-fly
This was one of that annoying old design mistakes where Doom and Heretic features were poorly merged together. The Heretic Gargoyle uses very similar coding but performs a subtly different action when actually hitting another actor. This different action was made the default, even for the Lost Soul.
It has now been changed that both monsters use their original action, being distinguished by an actor flag. For compatibility with custom definitions Heretic's behavior, which has been the default in ZDoom will be the preferred one. The one of the Lost Soul can be reactivated by a flag.
The use type is being used for texture lookup, so changing this alters the texture lookup rules and may cause return of incorrect textures.
This also ensures that context depending upscaling rules get used, because FontChars are separate from regular textures.
Most importantly, specifying a patch may optionally disallow showing the autor's name - this is for cases where a styled patch gets used for English but text-based translations of the map name should still be possible.
* sprite offset definitions, which are IWAD dependent
* Freedoom's decal overrides
* conversation ID definitions for the Strife teasers
* the fallback BigFont now can also be loaded by IWADs which declare themselves as GAME_Heretic or GAME_Hexen.
