function is called that returns a the shader upload code for that uniform.\n// Shader upload code is automagically generated with these parsers.\n// If no parser is valid then the default upload functions are used.\n// exposing Parsers means that custom upload logic can be added to pixi's shaders.\n// A good example would be a pixi rectangle can be directly set on a uniform.\n// If the shader sees it it knows how to upload the rectangle structure as a vec4\n// format is as follows:\n//\n// {\n// test: (data, uniform) => {} <--- test is this code should be used for this uniform\n// code: (name, uniform) => {} <--- returns the string of the piece of code that uploads the uniform\n// codeUbo: (name, uniform) => {} <--- returns the string of the piece of code that uploads the\n// uniform
