Private members of the FrameBuffer class are split between FrameBuffer
and FrameBuffer::Private. There was no real justification for this
split, and keeping some members private in the FrameBuffer class causes
multiple issues:
- Future modifications of the FrameBuffer class without breaking the ABI
may be more difficult.
- Mutable access to members that should not be modified by applications
require a friend statement, or going through the Private class.
Move all remaining private members to the Private class to address the
first issue, and add a Private::metadata() function to address the
second problem.
