62072838c9 cogl: Remove midscene tracking
Midscene tracking was used at a time that some Cogl users
could call random OpenGL API without going through Cogl.
That is not allowed anymore, and certainly not done by
Mutter and GNOME Shell.

Remove midscene tracking from CoglFramebuffer.

c5b7d73ce2 cogl/journal: Track dither
For the exact same reason that previous commit added
viewport tracking, also add dither state tracking and
avoid flushing the journal even more.

0556138b9f cogl/journal: Track viewport
CoglJournal tracks a few OpenGL states so that they can
be batch-applied if necessary. It also has a nice property
of allowing purely CPU-based glReadPixels() when the scene
is composed of simple rectangles.

However, the current journal implementation leaves various
other GL states out, such as dithering and the viewport.
In Clutter, that causes the journal to be flushed when
picking, touching the GPU when we didn't really need to.

Track the viewport of the framebuffer in the journal so that
we can avoid flushing the journal so often.

d57dbe1d4c framebuffer: Fix clip tracking in the unclipped case
Leaving the clip bounds untouched means that it will retain the stale value
of whatever it was when we last had a clip; reset it so that it contains the
full framebuffer contents instead.

5d646a5d6f cogl/framebuffer: Check buffer bits before modifying it
CoglFramebuffer checks the passed buffer bits in order to
detect when the fast path (that uses the journal) should
be used.

However, it also modifies one of the buffer bits that is
checked for the fast path, meaning we never actually hit
the fast path on cogl_framebuffer_cleaf4f().

Check the depth and color buffer bits before modifying them.

959a418cc3 Replace CoglEuler by graphene_euler_t
As the first step into removing Cogl types that are covered by
Graphene, remove CoglEuler and replace it by graphene_euler_t.

This is a mostly straightforward replacement, except that the
naming conventions changed a bit. Cogl uses "heading" for the
Y axis, "pitch" for the X axis, and "roll" for the Z axis, and
graphene uses the axis themselves. That means the 1st and 2nd
arguments need to be swapped.

Also adapt the matrix stack to store a graphene_euler_t in the
rotation node -- that simplifies the code a bit as well.

cada2b54fe Add Graphene dependency
Graphene is a small library with data types and APIs
specially crafted to computer graphics. It contains
performant implementations of matrices, vectors, points
and rotation tools. It is performance because, among
other reasons, it uses vectorized processor commands
to compute various operations.

Add Graphene dependency to Mutter.

8e204e036a cogl: Add a notion of pixel format planes
As we will start adding support for more pixel formats, we will need to
define a notion of planes. This commit doesn't make any functional
change, but starts adding the idea of pixel formats and how they (at
this point only theoretically) can have multple planes.

Since a lot of code in Mutter assumes we only get to deal with single
plane pixel formats, this commit also adds assertions and if-checks to
make sure we don't accidentally try something that doesn't make sense.

6ed5d2e2b4 cogl: Remove GLX "threaded swap wait" used on Nvidia
Threaded swap wait was added for using together with the Nvidia GLX
driver due to the lack of anything equivalent to the INTEL_swap_event
GLX extension. The purpose was to avoid inhibiting the invocation of
idle callbacks when constantly rendering, as the combination of
throttling on swap-interval 1 and glxSwapBuffers() and the frame clock
source having higher priority than the default idle callback sources
meant they would never be invoked.

This was solved in gbz#779039 by introducing a thread that took care of
the vsync waiting, pushing frame completion events to the main thread
meaning the main thread could go idle while waiting to draw the next
frame instead of blocking on glxSwapBuffers().

As of https://gitlab.gnome.org/GNOME/mutter/merge_requests/363, the
main thread will instead use prediction to estimate when the next frame
should be drawn. A side effect of this is that even without
INTEL_swap_event, we would not block as much, or at all, on
glxSwapBuffers(), as at the time it is called, we have likely already
hit the vblank, or will hit it soon.

After having introduced the swap waiting thread, it was observed that
the Nvidia driver used a considerable amount of CPU waiting for the
vblank, effectively wasting CPU time. The need to call glFinish() was
also problematic as it would wait for the frame to finish, before
continuing. Due to this, remove the threaded swap wait, and rely only on
the frame clock not scheduling frames too early.

7e8a864992 cogl: Remove unused cogl-gles2 API
This was introduced in:

    commit 010d16f647
    Author: Robert Bragg <robert@linux.intel.com>
    Date:   Tue Mar 6 03:21:30 2012 +0000

        Adds initial GLES2 integration support

        This makes it possible to integrate existing GLES2 code with
        applications using Cogl as the rendering api.

That's maybe a reasonable thing for a standalone cogl to want, but our
cogl has only one consumer. So if we want additional rendering out of
our cogl layer, it makes more sense to just add that to cogl rather than
support clutter or mutter or the javascript bindings creating their own
GLES contexts.

45289b3d65 cogl: Allow glBlitFramebuffer between onscreen/offscreen
Depends on "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"

Allow blitting between onscreen and offscreen framebuffers by doing the y-flip
as necessary. This was not possible with ANGLE, but now with ANGLE gone,
glBlitFramebuffer supports flipping the copied image.

This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer.

6df34eb4b7 cogl: Relax formats on glBlitFramebuffer
Depends on: "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"

As a possible ANGLE implementation is not longer limiting the pixel format
matching, lift the requirement of having the same pixel format.

We still cannot do a premult <-> non-premult conversion during a blit, so guard
against that.

This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer if the formats do not
match exactly.

3e68c9e8fa cogl: Replace ANGLE with GLES3 and NV framebuffer_blit
ANGLE extensions are only provided by Google's Almost Native Graphics Layer
Engine (ANGLE) implementation. Therefore they do not seem too useful for
Mutter.

The reason to drop GL_ANGLE_framebuffer_blit support is that it has more
limitations compared to the glBlitFramebuffer in GL_EXT_framebuffer_blit,
GL_NV_framebuffer_bit, OpenGL 3.0 and OpenGL ES 3.0. Most importantly, the
ANGLE version cannot flip the image while copying, which limits
_cogl_blit_framebuffer to only off-screen <-> off-screen copies. Follow-up work
will need off-screen <-> on-screen copies.

Instead of adding yet more capability flags to Cogl, dropping ANGLE support
seems appropriate.

The NV extension is added to the list of glBlitFramebuffer providers because it
provides the same support as ANGLE and more.

Likewise OpenGL ES 3.0 is added to the list of glBlitFramebuffer providers
because e.g. Mesa GLES implementation usually provides it and that makes it
widely available, again surpassing the ANGLE supported features.

Follow-up patches will lift some of the Cogl assumptions of what
glBlitFramebuffer cannot do.

d7d75dd8e7 cogl-trace: Include cogl-trace.h even when not tracing

often compilers warn you if you haven't:

```

In this case the function declarations were not included because
`HAVE_TRACING` isn't defined. But we should still include `cogl-trace.h`
because it handles the case of `HAVE_TRACING` not being defined and
correctly still declares the functions defined in `cogl-trace.c`.

cogl: Add libsysprof capture based tracing
Add the ability to add tracing instrumentation to the code. When
enabled, trace entries will generate a file with timing information
that will be processable by sysprof for generating visualization of
traces over time.

While enabled by default at compile time, it is possible to disable the
expansion of the macros completely by passing --disable-tracing to
./configure.

Tracing is so far only actually done if actually enabled on explicitly
specified threads.

This will be used by Mutter passing the write end of a pipe, where the
read end is sent to Sysprof itself via the D-Bus method 'Capture()'.

By passing that, we have to detect EPIPE that is sent when Sysprof stops
recording. Fortunately, we already ignore the signal at meta_init(), so
no need to add a custom signal handler.
