    vtkLineIntegralConvolution2D_fs1.glsl was using bReset in an expression to
    compute tcord0. As it was not a conditional, there was a texture fetch on a
    uninitialized texture. The result could be NaN or undefined and this value
    multiplied by (1-bReset) would lead to a NaN or undefined result that would
    propagate to the final value of tcord0 even if the actual value of (1-bReset)
    is 0. The fix is to use a conditional statement instead.
