GstVideo-1.0.gir, double entries

Platform Language bindings

May it be possible to remove the doubled entries in

$ grep -A8 "member name=\"onefield\"" /usr/share/gir-1.0/GstVideo-1.0.gir

This is for gstreamer-1.16.2.

Unfortunately this gives redefinition errors for Nim.

And what do we think about member names starting with a digit?

$ grep -i -A8 "16_235" /usr/share/gir-1.0/GstVideo-1.0.gir
      <member name="16_235"
              value="2"
              c:identifier="GST_VIDEO_COLOR_RANGE_16_235"
              glib:nick="16-235">
        <doc xml:space="preserve"
             filename="gst-plugins-base-1.16.2/gst-libs/gst/video/video-color.h"
             line="33">[16..235] for 8 bit components. Chroma has
                [16..240] range.</doc>
      </member>

But well, the gst modules are full of names starting with digits, so it seems to be intended:

That’s something you need to handle in your bindings generation code. Similar to names that are keywords in the target language or otherwise names that are not allowed.
