Image filters: simplify filterInputGPU().

Image filters: simplify filterInputGPU().

Remove a call to canFilterImageGPU() / filterImageGPU() from 
filterInputGPU(). There's no reason to do this, since 
the subsequent filterImage() call will do it for us anyway. 
And this call actually defeats caching (as demonstrated by 
the attached bench).
