twice. Adding geometry combine so that background geometry objects
with the same color can be merged and rendered at once

dwrite: Add dwritesubtitleoverlay element
...
Adding new subtitle overlay element. It's a bin which is wrapping
two internal elements dwritesubtitlemux and dwritetextoverlay.

buffers and to attach the aggregated subtitle buffers on
video buffer as meta.
* dwritetextoverlay: Extracts/renders the subtitle meta and
discard the meta after rendering.
