Changes between Initial Version and Version 1 of Ticket #38205, comment 8

initial	v1
10	10
11	11	This is a little late, but libvpx is a video compression library used by ffmpeg, and ffmpeg is needed by gegl, which in turn is needed by gimp2. So it's 3 dependency levels down.
	12
	13	Edit: gegl actually lists ffmpeg as an optional dependency, not a needed one: http://www.gegl.org/#_dependencies
	14
	15	Perhaps the port for gegl could have its ffmpeg dependency moved to a variant? According to the link, libopenraw, libsdl, jpeg, openexr, and librsvg are also all optional dependencies; perhaps all of them could be moved to one big `+optional_dependencies` variant or something?
