Ivan Molodetskikh 432782d09a gtk4: Premultiply alpha in GL textures 
GTK expects GL textures to have premultiplied alpha. The ones we get
from GStreamer don't, leading to incorrect rendering of semitransparent
frames.

GTK 4.12 gained an API to set a different GL texture format, but it
won't help for older GTK versions. Plus, at the time of writing, it
causes a very slow download/upload path in GTK.

So, use a GTK GL shader node to premultiply the alpha without leaving
the GPU.
