  Status update:
  Incorporated changes from Peter's CL.
  Images load fine, video plays fine, no distorted colors. Things appear to work, but
  I'm seeing errors in the logs though when I play HDR video, my guess is they originate from glTexImage2D -

- Getting the same results, even after updating.
  Status:
  Ignoring the scanout errors, it's really only the GL_INVALID_FRAMEBUFFER_OPERATION error that remains in the logs. It prints about 10 lines of error the first time an HDR video is played, then never again. I would even consider committing now and worrying about it later
  But there is another problem where the brightness flickers when you switch between or hover over tabs. With 'Tint Composited Content' enabled, you can see the window is being composited at the same time. Could be a coincidence, or related to the flashing.
  The flashing does not occur when delegated compositing is disabled.

    return GL_RGBA16F_EXT;

- This line hasn't made any difference either way, I will probably remove it, but it's not what's causing the error.

  I'm going to keep this change even though it hasn't really had an effect because I do believe it's the correct format for glTexImage2D when requesting half float buffers.

  We had to add at least another colorspace to the wayland protocol. You will need to conditionally enable HDR on the version that you provided this color space otherwise old versions of ash will be running HDR when it is not fully supported.

- Done

- Patch Set #4, Line 51: GL_RGBA
  I wonder if this is correct

- I believe this should represent the data_format arg that would be passed into glTexImage2D() so should be GL_RGBA because RGBA16F includes three color channels and an alpha.

  But let me double check. There are a couple of data/internal format functions and it's possible I'm confused or the code is wrong.
