(The Raven license got removed from sc_man after checking that no Raven code is still present here, this file got a nearly complete overhaul over all those years.)
It can now be used from UDMF and ZScript.
To avoid clutter it doesn't allow setting the values individually but requires definition of a data record in TEXTURES.
colorization
{
DesaturationFactor <float>
Invert
AddColor <color>
ModulateColor <color>
BlendColor <color>, <mode> [, <alpha>]
}
Mode for BlendColor can be Alpha (normal translucent blending), as well as 3 special values taken from Build engine games: Screen, Overlay and HardLight.
It makes little sense exposing every minute detail of this through UDMF.
Setting it up that way is far too complicated. Using virtual textures that map to a real texture plus a colorization record should be far easier to use by mappers.
This also doesn't piggyback on the Doom64 color feature anymore and is completely separate, despite some redundancies.
This is still missing the texture definition part, though.
The main catch is now in D_DoomMain, only calling platform specific functions to handle the output for the error.
As a nice side effect, -norun can now be done without an exception, just by exiting D_DoomMain with a special exit code.
Now there is only one single entry point for both, instead of previously 2 entry and 4 exit points.
This also eliminates the explicit shutdown of ZMusic. Timidity++'s two buffers have been put in containers that self-destruct on shutdown and calling dumb_exit is not necessary because the only feature requiring it is not used by any code in the music library.
Instead of trying a homegrown way to avoid recursive exceptions, let's do it with the defined procedure C++ has for this case: call std::terminate.
This allowed removing some old hackery inherited from Boom and will now hopefully allow sanitizing the exit procedure to the point that it can be done without depending on exit handlers.
They were already clean of unwanted external references, but including this file made it hard to keep it that way.
This also moves a few useful definitions around to less 'dirty' headers.
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.
Precompilation of prefix header for GCC and Clang requires some efforts thanks to CMake which doesn't support this feature out of the box
Existing thirparty solutions must be tuned to our needs, and our configuration should be adjusted to a chosen module
