3ecb8bea22 basetextoverlay: Do not fail the negotiation if query fails
The allocation query failure doesn't mean that the negotiation
has failed as the element can allocate buffers itself.

Instead, only fail if the pads are flushing and the allocation
query failed.

76ce112994 basetextoverlay: schedule reconfigure on source pad when negotiation fails
The source pad might be flushing while negotiating, resulting in
set_caps or the ALLOCATION query failing. In this case set the
reconfigure flag on the source pad so that negotiation is retried on the
next buffer.

501a295fa1 basetextoverlay: remove unneeded cairo transparence setting
he code here:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1554

should make transparent the box that contains the text, I think this code is
not correct, it should be:

if (overlay->want_shading) {
    double alpha = overlay->shading_value / 255.0;
    cairo_paint_with_alpha (cr, alpha);
  }

however I think this code could be removed, we already do a shaded background,
why shade the box behind the text with cairo too? only one shading is needed so
we must shade with cairo or with methods like these:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1642

not both

a65b307349 basetextoverlay: properly fallback to non-overlay caps
When downstream claims to accept the overlay meta but fails to
provide it in the allocation query, properly fallback to setting
a new caps without the overlay meta as that is not going to be used.

Only do this if the original caps doesn't have the overlay already,
otherwise there isn't much that can be done.

e783a366cb textoverlay: Don't hold any mutexes while calling negotiate
It's not done in any other code calling negotiate and will cause deadlocks
as it is sending events and queries in the pipeline.

Specifically this pipeline was deadlocking:
gst-launch-1.0 videotestsrc ! textoverlay ! textoverlay ! fakesink

5fc94da399 textoverlay: remove code that can't be reached
If this code could ever be reached, it would leak
memory (CID 1231978), but gst_caps_get_features()
never returns NULL, so that can't happen.

a080c0ebbf basetextoverlay: rework caps negotiation
Make textoverlay negotiate caps more correctly.

1) Check what caps we received in the video-sink
2) If it already has the overlay meta -> use it directly
3) If it doesn't, textoverlay try adding the overlay meta and using it,
   if downstream doesn't support it, just use what is received in the
   video-sink
4) Check if the allocation query also supports the meta to enable
   really using it

Before it wasn't really doing renegotiation of any kind, just
re-checking if it should use the overlay meta or not

Also had to update the caps in the test as memory:SystemMemory seems
to be required when you use a caps feature otherwise intersection/subset
checks will fail.

ec7724c095 basetextoverlay: use correct segment for text
video time uses the 'segment' and the text time should use
the 'text_segment'.

If different segments are used for video and text it would

fb102419c7 pango: 3rd time's the charm. Fix attribute list handling.
Really really fix attribute list handling by taking a
copy of the original attributes that pango_attr_list_filter
can mutate, but keep the original around intact to restore
later.
