Make the title clip text border and shadow optional
Currently the text in a title clip is shown with a border and shadow which can be easily seen by setting the foreground color to transparent and the background color to some bright color. The user should have the option of disabling it in the middle pane > Title tab implemented in titleeditor.py.
BORDER
This requires some preparatory work in GStreamer so that GES.TitleClip's video element called GES.TitleSource exposes two "children properties" for these.
Start to follow how the outline-color
children property works by looking at ges-title-source.c
You'll find out it's linked to a textoverlay
element, which you can investigate with:
$ gst-inspect-1.0 textoverlay
SHADOW
In GES we need to expose the textoverlay:draw-shadow property right here.
Then in Pitivi you would need to call:
title_clip.set_child_property("draw-shadow", value)
That should be it, patches very welcome :-)
