Don't include the lazy precompiled.h everywhere, only what's required for the compilation unit. platform.h needs to be included instead to provide all essential defines and types. All includes use the relative path to the neo or the game specific root. Move all idlib related includes from idlib/Lib.h to precompiled.h. precompiled.h still exists for the MFC stuff in tools/. Add some missing header guards.

Decals are lightweight primitives for bullet / blood marks.
|
|
Decals with common materials will be merged together, but additional
|
|
decals will be allocated as needed. The material should not be
|
|
one that receives lighting, because no interactions are generated
|
|
for these lightweight surfaces.
|
|
|
|
FIXME: Decals on models in portalled off areas do not get freed
|
|
until the area becomes visible again.
