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.

/*

|
|
|
Any errors during parsing just set MF_DEFAULTED and return, rather than throwing
|
|
a hard error. This will cause the material to fall back to default material,
|
|
but otherwise let things continue.
|
|
|
|
Each material may have a set of calculations that must be evaluated before
|
|
drawing with it.
|
|
|
|
Every expression that a material uses can be evaluated at one time, which
|
|
will allow for perfect common subexpression removal when I get around to
|
|
writing it.
|
|
|
|
Without this, scrolling an entire surface could result in evaluating the
|
|
same texture matrix calculations a half dozen times.
|
|
|
|
Open question: should I allow arbitrary per-vertex color, texCoord, and vertex
|
|
calculations to be specified in the material code?
|
|
|
|
Every stage will definately have a valid image pointer.
|
|
|
|
We might want the ability to change the sort value based on conditionals,
|
|
but it could be a hassle to implement,
