While good in theory, a WYSIWYG rich text editor for large video frames
was unwieldy (and in many cases unhelpful). Instead the titler will
show plain text/HTML tags so the user can still write rich text but
without the unwieldy UI.
For a true WYSIWYG experience, we would probably need to write a true
graphical editor (a la Premiere's titler), but that's a later goal.
This titler will be sufficient in a good majority of cases and there
are plenty of dedicated graphics packages if more complex titling is
required for the timebeing.
