Subject : Pass correct texture hint for GPU raster
Author  : ericrk
Commit description:
  
Currently, ResourcePool creates all resources with
ResourceProvider::TEXTURE_HINT_IMMUTABLE. This is fine for SW raster,
however we should be using TEXTURE_HINT_IMMUTABLE_FRAMEBUFFER for GPU
raster. Using the correct flag passes additional information to ANGLE
via a GL extension and causes us to skip an unnecessary texture copy.
