Some client use subsurfaces with fully transparent single-pixel buffers
for various reasons, such as making it easier to order trees of
subsurfaces. As they are invisible we can simply ignore them in the

Recent improvements to llvmpipe made it possible to test dmabuf import
and offloading on vkms. Use our new client-buffer helper and the
presentation protocol to implement tests for simple offloading
scenarios.
Right now this is limited to the vkms default config, only providing us
with one primary and one cursor plane. In the future we can extend the
test to include more advanced scenarios.

Now that we are testing the more robust average error tolerance pretty
tightly, we can relax the tolerances on the maximum error which is more

Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
Maximum error is fragile: radeonsi on Polaris 11 has one error spike
that would force the the tolerances for everything to be much higher
than desired, and it masks changes to usual error levels.
Add a new condition to opaque_pixel_conversion: average two-norm error
statistic. The average is not as susceptible to outliers as maximum is.
We still keep the maximum error tolerance as well, to detect gross
outliers that might not sway the average enough to cause a test failure.
The new average error tolerances have been collected from the worst case
among the following + 0.01:
- GL renderer: Mesa Intel(R) HD Graphics 4600 (HSW GT2)
- GL renderer: AMD Radeon RX 550 Series (radeonsi, polaris11, ACO,
