We deduce whether to premul or unpremul based on the the input/output alpha types. This means we also now support unpremuling on write and premuling on read. Class-ify former struct GrPixelInfo. Remove origin and instead pass a flip bool to GrConvertPixels. Unifies read/write methods on GrSurfaceContext via automatic conversion of SkImageInfo to GrPixelInfo and making GrDirectContext an optional parameter.
