a49c98d8d8 tests: Don't continue if setup commands fail
Because POSIX sh was, with hindsight, not a particularly well-designed
programming language, if we don't 'set -e', then we'll respond to failure
of a setup command such as cd by carrying on regardless.

7af1043865 tests: Don't use TestEnvironment
The assumption here seems to be that it's an overlay onto the
current environment which would make sense; but the implementation in
gnome-desktop-testing currently removes all other environment variables
(see GNOME/gnome-desktop-testing#1). This causes test failure when the
tests are run in Debian's autopkgtest framework, possibly because PATH
is cleared.

87965b5ce2 cogl: Add support for partial update
Add support for a cogl function to set the damage_region on an onscreen
framebuffer.
The goal of this is to enable using the EGL_KHR_partial_update extension
which can potentially reduce memory bandwidth usage by some GPUs,
particularly on embedded GPUs that operate on a tiling rendering model.

"GL_EXT_discard_framebuffer".

With this fix, cogl_gl_framebuffer_fbo_discard_buffers can actually call
glDiscardFramebufferEXT.

A trace "anchor" is a trace head (CoglTraceHead) that is placed in a
certain scope (e.g. function scope), but then only triggered in another
scope, e.g. a condition.

This makes it possible to have optional trace instrumentation, that is
enabled only given e.g. a debug flag.

5e45dc15b6 cogl/renderer: Add API to bind the right EGL API
We need to call eglBindAPI() with GLES before we setup the secondary
GPU blit. We've been lucky not really needing this, as it has been
GLES default, which is what the secondary blit uses, in order to not
depend on the default, or if we want to create the secondary blit
objects after initializing cogl, we must make sure to bind the right API
at the right time.

As we need to bind the GLES API when setting up the secondary blit, we
need to make sure that cogl gets the right API bound when that's done,
so Cogl can continue working. For this, add a "bind_api()" method on the
CoglRenderer object, that will know what API is correct to bind.

936696afcf cogl/winsys-glx: Request 2 stencil bits
Just like we do on EGL. Two bits are required because
`cogl-clip-stack-gl.c` needs each stencil buffer element to be able to
count from 0 to 2.

This mistake probably went unnoticed because:

 * Drivers usually provide more than 1 anyway; and

 * Optimizations in `cogl-clip-stack-gl.c` avoid calling the code that
   needs to count past 1 in most cases.

216bb7f960 cogl/clip-stack-gl: Set glStencilMask correctly for clip regions
Previously we were using a mask of 0x1 for the lifetime of the stencil.
This was wrong for two reasons:

  * The intersection algorithm needs to count up to a maximum 2, so a
    mask of 1 would clamp to 1 instead. Then decrementing all pixels
    resulted in all pixels being zero even though we want some to be 1.
    So the stencil then blocked some color buffer pixels being rendered.

  * The lifetime of the mask was too long. By leaving it non-zero at
    the end of the function we could accidentally end up modifying the
    stencil contents during our later color buffer paints.

This fixes faulty rendering of some actors seen in gnome-shell with
test case: `env COGL_DEBUG=stencilling`

7d88386ee1 mutter-cogl.test: Use xvfb-run to run the cogl tests
The cogl tests need to run with a display server set, however since we
use TestEnvironment, only the listed env variables will be exposed to
the test and so no DISPLAY will be set when launching it with
gnome-desktop-testing-runner.

As per this, just run the tests using xvfb-run so that we match what's
happening in CI and we ensure that the tests are run in a safe

4810164885 cogl: Make presentation time always MONOTONIC
This concerns only the cases when the presentation timestamp is received
directly from the device (from KMS or from GLX). In the majority of
cases this timestamp is already MONOTONIC. When it isn't, after this
commit, the current value of the MONOTONIC clock is sampled instead.

The alternative is to store the clock id alongside the timestamp, with
possible values of MONOTONIC, REALTIME (from KMS) and GETTIMEOFDAY (from
GLX; this might be the same as REALTIME, I'm not sure), and then
"convert" the timestamp to MONOTONIC when needed. An example of such a
conversion was done in compositor.c (removed in this commit). It would
also be needed for the presentation-time Wayland protocol. However, it
seems that the vast majority of up-to-date systems are using MONOTONIC
anyway, making this effort not justified.

d8606829c4 cogl: Report presentation time in microseconds
KMS and GLX device timestamps have microsecond precision, and whenever
we sample the time ourselves it's not the real presentation time anyway,
so nanosecond precision for that case is unnecessary.

The presentation timestamp in ClutterFrameInfo is in microseconds, too,
so this commit makes them have the same precision.
