Brian Salomon ecbb0fb2d5 Simplify view getters on GrTextureProducer. 
The only thing that affects the view returned is whether it ought to
be MIP mapped or not. So don't take a whole GrSamplerState.

The view() function won't ever change the colortype so just query
GrTextureProducer rather than having view() return a tuple.

The rest is transitively reaching through callers and callees of
GrTextureProducer::view() to only pass filter or GrMipMapped instead of
GrSamplerState. Also, some params that indicate whether MIPs are
requested are changed from bool to GrMipMapped. And some minor style
stuff (mainly de-yoda-ifying GrMipMapped checks, using
GrSurfaceProxyView operator bool()).
