[SRWorks 0.9.0.3] Fix the issue that see-thru screen is too bright when using Unity plugin

[akira fan]

If you use Linear Color Space for your Unity project, the see-thru screen will be too bright.

You can use GammaToLinearSpace() in StencilUnlitTexture.shader(ViveSR\Shaders\Resources\StencilUnlitTexture.shader) to fix this issue.
 

Here is the code snippet

float4 frag (fInput fIn) : SV_Target
{
    return float4(GammaToLinearSpace(tex2D(_MainTex, fIn.uvCoord).rgb), 1);
}

 Thanks
