[Spice-devel] [PATCH v4 0/5] Add OpenGL scanout drawing

[Marc-André Lureau]

The following series implements the x11 client-side support for
local-only shared OpenGL scanout rendering.

The implementation doesn't rely on gtkglarea since:
- it's quite recent (3.16 while rhel7 is currently 3.14)
- using gtkglarea isn't possible without either uncovenient API
  changes (new widget) or ABI break (SpiceDisplay widget to inherit
  from something more flexible than GtkDrawingArea)
- gtkglarea uses various gdk backends to setup GL context, such as
  glx, however dmabuf import requires egl.

I have a gtk3/gtkglarea-based branch, which will bring wayland
support. I would suggest to do first a release with gtk2/x11/egl
support before deprecating gtk2 and bumping gtk requirements.

v3->v4:
- fix rebase

v2->v3: after code review session with the team
- remove gslice usage
- drop gles in favour of desktop gl (probably more appropriate)
- explain the rationale for boxed scanout property and const getter in
  commit details
- some indent fixes

v1->v2:
- add some error handling code, fix gl objects leaks
- improve egl code to be compatible with future wayland series
- misc spellings

  Add spice_channel_unix_read_fd()
  build-sys: check for epoxy-egl support
  glib: add local GL scanout support
  gtk: add spice-widget GL scanout support
