% The main objective of this test is to see if operations for SM1 vertex shaders work, because they % have a different instruction set than pixel shaders. % Considerations so that the vertex shader output matches the pixel shader input properly on all % backends: % - sv_position must be the last field in the output signature. % - the d3d9 backend, on Windows, clamps the value of the COLORX semantics before passing it to % the pixel shader, so their values must be between 0.0 and 1.0.
