Gerd Hoffmann d2329237af ui/egl: fix framebuffer reads
Fix egl_fb_read() to use the (destination) surface size instead of the
(source) framebuffer source for glReadPixels.  Pass the DisplaySurface
instead of the pixeldata pointer to egl_fb_read() to make this possible.

With that in place framebuffer reads work fine even if the surface and
framebuffer sizes don't match, so we can remove the guest-triggerable
asserts in egl_scanout_flush().

Chen Zhang 051a0cde7b ui/egl-helpers: Augment parameter list of egl_texture_blend() to convey scales of viewport
This would help gtk-egl display showing scaled DMABuf cursor images when
gtk window was zoomed. A default scale of (1.0, 1.0) was presumed for
call sites where no scaling is needed.

Gerd Hoffmann 952e5d584f egl-headless: add egl_create_context
We must set the correct context (via eglMakeCurrent) before
calling qemu_egl_create_context, so we need a thin wrapper and can't
hook qemu_egl_create_context directly as ->dpy_gl_ctx_create callback.

Erik Skultety 91e61947eb ui: Allow specifying 'rendernode' display option for egl-headless
As libvirt can't predict which rendernode QEMU would pick, it
won't adjust the permissions on the device, hence QEMU getting
"Permission denied" when opening the DRI device. Therefore, enable
'rendernode' option for egl-headless display type.

Gerd Hoffmann 54d208ffda Add gles support to egl-helpers, wire up in egl-headless and gtk.
Add support for OpenGL ES to egl-helpers.  Wire up the new option for
egl-headless and gtk UIs.  egl-headless actually works fine.  gtk hits a
not-yet implemented code path in libEGL when trying to use gles mode:

  libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.

(This is mesa 17.2.3).

Gerd Hoffmann b09169282b egl-headless: cursor_dmabuf: handle NULL cursor
The cursor dmabuf can be NULL, in case no cursor defined by the guest.
Happens for example when linux guests show the framebuffer console.

Gerd Hoffmann 74083f9c01 egl: misc framebuffer helper improvements.
Rename the functions to to say "setup" instead of "create" because they
support being called multiple times on the same egl framebuffer.

Properly delete unused textures, update function interfaces to support
this.

Gerd Hoffmann bb1599b64c opengl: add egl-headless display
Add egl-headless user interface.  It doesn't provide a real user
interface, it only provides opengl support using drm render nodes.
It will copy back the bits rendered by the guest using virgl back
to a DisplaySurface and kick the usual display update code paths,
so spice and vnc and screendump can pick it up.

Use it this way:
  qemu -display egl-headless -vnc $display
  qemu -display egl-headless -spice gl=off,$args

Note that you should prefer native spice opengl support (-spice
gl=on) if possible because that delivers better performance.
