None of which will require a rewrite to support.  In fact, Emacs 29
already supports precision mice, high definition displays, multitouch
trackpads, and digitizers.  On X, both the non-Cairo and Cairo builds
make use of hardware acceleration whenever available through both the
Glamor component of the X server and the X render extension.

NS also makes use of hardware acceleration, and IIUC GDI (which is used
in MS-Windows) is also hardware accelerated.

Gecko is still mostly C++, and hasn't gone through much of a rewrite
either.  (But please take the discussion about Gecko to emacs-tangents.)
