Comments:

    Header file with lots of useful macros, types, and functions for use

		with textures and render-to-texture-buffer effects in DirectX.



Example Macro Usages:

	Texture-declaration Macros:

		FILE_TEXTURE_2D(SurfTexture,SurfSampler,"myfile.dds") // simple 2D wrap texture

		FILE_TEXTURE_2D_MODAL(SpotTexture,SpotSampler,"myfile.dds",CLAMP) // user-defined addr mode

	RenderTarget Texture-declaration Macros:

		DECLARE_QUAD_TEX(ObjTexture,ObjSampler,"A8R8G8B8")

		DECLARE_QUAD_DEPTH_BUFFER(DepthTexture,"D24S8")

		DECLARE_SIZED_QUAD_TEX(GlowTexture,GlowSampler,"A8R8G8B8",0.5) // scaled versions of above

		DECLARE_SIZED_QUAD_DEPTH_BUFFER(DepthTexture,"D24S8",0.5)

		DECLARE_SIZED_TEX(BlahMap,BlahSampler,"R32F",128,1)	// address mode is "clamp"

		DECLARE_SQUARE_QUAD_TEX(ShadTexture,ShadObjSampler,"A16R16G16B16F",512) // for shadows etc

		DECLARE_SQUARE_QUAD_DEPTH_BUFFER(ShadDepth,"D24S8",512)

	Data types used in shaders:

		QUAD_REAL & QUAD_REAL# -- defaults to HALF but you can define QUAD_REAL float

			before #including "Quad.fxh" either by explicitly declaring all the QUAD_REAL types

			yourself, or #define-ing the symbol QUAD_FLOAT

	Flags (define before #including "Quad.fxh"):

		TWEAKABLE_TEXEL_OFFSET	// shows in paramter panel

		NO_TEXEL_OFFSET	// disables



Structure:

	QuadVertexOutput -- used by shaders, defines simple connection for "Draw=buffer" VS and PS



Shader Functions for "Draw=buffer" passes:

	QuadVertexOutput ScreenQuadVS():

		standard vertex shader for screen-aligned quads

	QUAD_REAL4 TexQuadPS(QuadVertexOutput IN,uniform sampler2D InputSampler)

		pass this pixel shader a sampler -- will draw it to the screen

	QUAD_REAL4 TexQuadBiasPS(QuadVertexOutput IN,uniform sampler2D InputSampler,QUAD_REAL TBias)

		Same as above, but uses tex2Dbias()



Utility Functions for Texture-Based Lookup Tables:

	QUAD_REAL scale_lookup(QUAD_REAL Value,const QUAD_REAL TableSize)

	QUAD_REAL2 scale_lookup(QUAD_REAL2 Value,const QUAD_REAL TableSize)

	QUAD_REAL3 scale_lookup(QUAD_REAL3 Value,const QUAD_REAL TableSize)

Other Utility Functions:

	QUAD_REAL4 premultiply(QUAD_REAL4 C)

	QUAD_REAL4 unpremultiply(QUAD_REAL4 C) // uses macro value NV_ALPHA_EPSILON



Global Variables:

	QUAD_REAL QuadTexOffset // reconciles difference between pixel and texel centers

	QUAD_REAL2 QuadScreenSize // VIEWPORTPIXELSIZE, contains dimensions of render window
