Some platforms (e.g., Intel SKL+) support a programmable background canvas
color below the hardware planes. For more details, see the cover letter for
the previous version of the series posted here:
https://lists.freedesktop.org/archives/intel-gfx/2015-October/078687.html
I haven't made any updates to libdrm or IGT since the last update, so I'm only
reposting updates of the kernel patches; use the link above to get to the
corresponding libdrm/igt changes.
Note that this series isn't mergeable yet since we don't (yet) have an open
source userspace that can make use of it. Eventual userspace candidates for
this functionality might be Weston, ChromeOS, or Android hwcomposer.
