That is true, thanks to the allocateBuffer callback.  For the Android
case, adding pbuffer support essentially changes only several lines of
code.  But looking at droid_get_buffers_with_format or the loop in
dri2_get_buffers_with_format in platform_wayland.c, some cleanups are
needed to find a place for the shared pbuffer getbuffers
implementation.
