Standalone shadercompile, that doesn't depend on valve libraries and supports x64. Also removes dependencies on external tools (no perl or DxSdk)

ShaderCompile.exe [OPTIONS] -ver n -shaderdir src_dir shader.fxc

-ver ARG Sets shader version, required
-shaderpath ARG Base path for shaders, required
-crc Calculate crc for shader
-dynamic Generate only header
-force Skip crc check during compilation
-threads ARG Number of threads used, defaults to core count
-h, -help Shows help
-verbose Verbose file cache and final shader info
-verbose2 Verbose compile commands
-verbose_preprocessor Enables preprocessor debug printing
-disable-optimization, /Od Disables shader optimization
-disable-preshader, /Op Disables preshader generation
-no-flow-control, /Gfa Directs the compiler to not use flow-control constructs where possible
-prefer-flow-control, /Gfp Directs the compiler to use flow-control constructs where possible
-partial-precision, /Gpp Compiles shader with partial precission
-no-validation, /Vd Skips shader validation

All shader models starting from PS2.b/VS2.0

Valid options for -ver

20 ps2b/vs20
30 ps30/vs30

This assumes you have "clean" Source SDK2013 project.

1. In game_shader_dx9_base.vpc replace $AdditionalIncludeDirectories "$BASE;fxctmp9;vshtmp9;" with $AdditionalIncludeDirectories "$BASE;include" , shader headers will be now located in more sensible place
2. Replace cshader.h in public/shaderlib with one from this repo, if you are using VS2013 compiler use the one from VS2013 folder
3. Place ShaderCompile.exe and process_shaders.ps1 to devtools/bin folder where vpc.exe is located
4. Replace buildshaders.bat with one from this repo
5. In buildsdkshaders.bat, remove from all commands -dx9_30 so

   %BUILD_SHADER% stdshader_dx9_30 -game %GAMEDIR% -source %SOURCEDIR% -dx9_30 -force30 

   looks like

   %BUILD_SHADER% stdshader_dx9_30 -game %GAMEDIR% -source %SOURCEDIR% -force30

6. Optionally remove all perl scripts for compiling shaders from devtools/bin, as they will be never used again
