Compilation error fix.

[johste93]

To make this work in Unity 2021.3 I had to replace all instances of

if (_IsUnlit == 0.0f)
{
    // Lighting
    finalColor = CombinedShapeLightShared(finalColor, maskColor, i.screenPos);
}

with:

if (_IsUnlit == 0.0f)
{
    // Lighting
    SurfaceData2D surfaceData;
    InputData2D inputData;
    surfaceData.albedo = finalColor.rgb;
    surfaceData.alpha = 1;
    surfaceData.mask = maskColor;
    inputData.uv = i.screenPos;
    finalColor = half4(CombinedShapeLightShared(surfaceData, inputData).rgb, finalColor.a);
}

Shader error in 'Game/S_BresenhamMultiLineRenderer2D': variable 'inputData' used without having been completely initialized at line 156 (on d3d11)

Not sure if this fixes it, but I used ZERO_INITIALIZE(InputData2D, inputData); before inputData.uv = i.screenPos;
