41Description:
42
43Shader execution tests render a grid of quads filling entire viewport with
44the shader being tested. Fragment shader includes a comparison against
45pre-computed reference. Fragment color is either white or black depending
46on whether the result were correct or not.
47
48Negative tests try to compile the given shader and expect compilation
49to fail.
