These cause ambiguous compiler reference errors on some GCC versions.
And, the errors seem right. But, newer versions of clang seem to resolve
that ambiguity by also checking if the references to the types are also
references to identical types.
Per the chat with Jim, also added the Dl prefix to those types.
No change in functionality. Just a rename of the types and removal of
the now unnecessary typedefs.
Flow is a simple compositor based on Skia that the Flutter engine uses to cache
recorded paint commands and pixels generated from those recordings. Flow runs on
the raster thread and uploads information to Skia.
