/** Shader Definitions
* - Only one technique, any number of passes.
* - Technique must be named 'Draw'.
* - Parameters are split by the last underscore (_) to determine if it is a special parameter or not.
*
* Predefined Parameters:
* - ViewProj: The current view projection matrix (float4x4).
* - ViewSize: The current rendered size (float2).
* - ViewSizeI: The current rendered size as an int (int2).
* - Time: Time passed during total rendering in seconds (float).
* - TimeActive: Time since last activation (float).
* - image: The source being filtered (texture2d).
*
* Texture Special Parameters:
* - $(name)_Size: Texture Size (float2).
* - $(name)_SizeI: Texture Size (int2).
* - $(name)_Texel: Texture Texel Size (1/Texture Size) (float2).
