	// results. The shader itself will calculate results based on input data and compare them to the expected results in the second
	// buffer, instead of verifying results on the CPU.
	//
	// The test function will return the color passed to it if the obtained results match the expected results, and will return (0.5,
	// 0.5, 0.5, 1.0) if they do not. For graphic stages, this returned color will be used to draw things and we can verify the output
	// image as usual with the graphics shader test utils. For compute shaders, this does not work.
	//
	// In this case, we will pass black as the input color for the test function, and will verify it returns black. We will write a
	// single integer in an output storage buffer as a boolean value indicating if the returned color matches the input color, to be
	// checked after the shader runs. Roughly equivalent to the following GLSL code:
	//
	//      layout(binding = 2) buffer BlockType { int values[]; } block;
	//
	//      vec4 testfun(in vec4 param);

//  'S': create scalar test
//  'V': create vector test
//
//  'I': create integer test
//  'U': create unsigned integer test
//
//  '8': create 8-bit test
//  '1': create 16-bit test

//
//  'W': bit width of some parameters in bit field and shift operations can be different from Result and Base
//  'N': create 16-bit tests without 'test_high_part_zero' variants
