% 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.
