// Quick try at doing a "print value" node for Unity ShaderGraph.
// Tested on Unity 2019.2.17 with ShaderGraph 6.9.2.
//
// Use with CustomFunction node, with two inputs:
// - Vector1 Value, the value to display,
// - Vector2 UV, the UVs of area to display at.
// And one output:
// - Vector4 Color, the color.
// Function name is DoDebug.

// When creating shaders for Universal Render Pipeline you can you the ShaderGraph which is super AWESOME!
// However, if you want to author shaders in shading language you can use this teamplate as a base.
// Please note, this shader does not necessarily match perfomance of the built-in URP Lit shader.
