qzdoom/src/g_shared/a_artifacts.cpp
Christoph Oelckers 231e7a1c6d - added a new render style 'Shadow'. Essentially it's just a black translucent stencil with an alpha of 0.3. The purpose of this style is to be used as a software renderer approximation of GZDoom's spectre effect.
- allow setting 'Shadow' as default fuzz effect
- changed CVAR conversion that strings 'false' and 'true' get evaluated as integers 0 and 1 respectively so that changing boolean CVARs to int does not destroy their values.
