Originally this was inplace so that we wouldn't simply migrate the
target away from the GPU whenever we inspected results. That is no
longer a problem and so we can speed up the tests by skipping the
temporary.

We shouldn't just discard the mask if the user requests that we render
the glyphs through a low bitdepth mask - and in doing so we should also
be careful not to improve the bitdepth of that mask (since we don't take
into account the extra quantisation desired).

Since the first flip may require a fixup, we will only really know with
the second flip whether we can start a flip chain with different tiling.

As the test presumes we can queue all the modulus queries within the
same vblank, we can improve matters by synchronizing to the next vblank
first.

When computing the delay for the fake flip, compensate for any time
elapsed since the last frame in order to hit the desired vblank more
accurately. A side-effect of this is that we may now compute 0 delay
timers which require special handling.

In order to have outstanding WaitMSC when the Client quits or the Window
is destroyed, we need to use the xcb version so as not to immediately
block on the play.
And also print keepalive dots to console as test progresses.

When the xserver is fixed and we no longer block for ever inside the
test, we can see that the test itself falsely reports failure!

The kernel caps the number of vblanks per client to 128. There are
already reports from the wild that Present clients are running foul of
that limit, so supplement it with a timer fallback.

To do SwapBuffers correctly requires a Swap/Get buffers combination, and
this is easiest using xcb rather than xlib.

A slightly more complex patch to disable the SHM based tests of
lowlevel-blt-bench when MIT-SHM support is not available at compile
time.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
Since 37ac34c4e4, lowlevel-blt-bench
requires SHM support, so only compile it if we detect such during
configure.

Applications are starting to use PDF operators, so far I have spotted
multiply, dodge and lighten.
