fInfo is constructed based on initial generator->getInfo(). However, as
colortype changed in generator, and fInfo size == geninfo size, using geninfo
here.

     } else {
         // need to handle subsetting, so we first generate the full size version, and then
         // "read" from it to get our subset. See https://bug.skia.org/4213
