cogl tests: Show the actual output from tests if VERBOSE is set

Writing tests' output to a log file makes them difficult to debug when the test might be running on an autobuilder or CI system where only stdout/stderr are recorded. This is particularly troublesome if a failure is only reproducible on a particular autobuilder. Recent Automake versions have the convention that detailed output from failing tests is written to stdout/stderr, not just to log files, when the VERBOSE environment variable is set; borrow that convention as a trigger for producing detailed test output. This was originally cogl!14, but applies equally to mutter's fork of cogl. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1273 Signed-off-by: Simon McVittie <smcv@debian.org>

-# Style
-
-The coding style used is primarily the GNU flavor of the [GNOME coding
-style][gnome-coding-style], with some additions described below.
-
-## General
-
- * Use this code style on new code. When changing old code with a different
-   code style, feel free to also adjust it to use this code style.
-
- * Use regular C types and `stdint.h` types instead of GLib fundamental
-   types, except for `gboolean`, and `guint`/`gulong` for GSource IDs and
-   signal handler IDs. That means e.g. `uint64_t` instead of `guint64`, `int`
-   instead of `gint`, `unsigned int` instead of `guint` if unsignedness
-   is of importance, `uint8_t` instead of `guchar`, and so on.
-
- * Try to to limit line length to 80 characters, although it's not a
-   strict limit.
-
- * Usage of `g_autofree` and `g_autoptr` is encouraged. The style to use is
-
-    ```c
-    g_autofree char *text = NULL;
-    g_autoptr (MetaSomeThing) thing = NULL;
-
-    text = g_strdup_printf ("The text: %d", a_number);
-    thing = g_object_new (META_TYPE_SOME_THING,
-                          "text", text,
-                          NULL);
-    thinger_use_thing (rocket, thing);
-    ```
-
- * Declare variables at the top of the block they are used, but avoid
-   non-trivial logic among variable declarations. Non-trivial logic can be
-   getting a pointer that may be `NULL`, any kind of math, or anything
-   that may have side effects.
-
- * Instead of boolean arguments in functions, prefer enums or flags when
-   they're more expressive. The naming convention for flags is
-
-    ```c
-    typedef _MetaSomeThingFlags
-    {
-      META_SOME_THING_FLAG_NONE = 0,
-      META_SOME_THING_FLAG_ALTER_REALITY = 1 << 0,
-      META_SOME_THING_FLAG_MANIPULATE_PERCEPTION = 1 << 1,
-    } MetaSomeThingFlags;
-    ```
-
- * Use `g_new0 ()` etc. instead of `g_slice_new0 ()`.
-
- * Initialize and assign floating point variables (i.e. `float` or
-   `double`) using the form `floating_point = 3.14159` or `ratio = 2.0`.
-
-## Header (.h) files
-
- * The return type and `*` are separated by a space.
- * Function name starts one space after the last `*`.
- * Parenthesis comes one space after the function name.
-
-As an example, this is how functions in a header file should look like:
-
-```c
-gboolean meta_udev_is_drm_device (MetaUdev    *udev,
-                                  GUdevDevice *device);
-
-GList * meta_udev_list_drm_devices (MetaUdev  *udev,
-                                    GError   **error);
-
-MetaUdev * meta_udev_new (MetaBackendNative *backend_native);
-```
-
-## Source code
-
-Keep functions in the following order in source files:
-
-  1. GPL header
-  2. Enums
-  3. Structures
-  4. Function prototypes
-  5. `G_DEFINE_TYPE()`
-  6. Static variables
-  7. Auxiliary functions
-  8. Callbacks
-  9. Interface implementations
-  10. Parent vfunc overrides
-  11. class_init and init
-  12. Public API
-
-### Structures
-
-Each structure field has a space after their type name. Structure fields aren't
-aligned. For example:
-
-```c
-struct _MetaFooBar
-{
-  MetaFoo parent;
-
-  MetaBar *bar;
-  MetaSomething *something;
-};
-```
-
-### Function Prototypes
-
-Function prototypes must be formatted just like in header files.
-
-### Overrides
-
-When overriding parent class vfuncs, or implementing an interface, vfunc
-overrides should be named as a composition of the current class prefix,
-followed by the vfunc name. For example:
-
-
-```c
-static void
-meta_bar_spawn_unicorn (MetaParent *parent)
-{
-  /* ... */
-}
-
-static void
-meta_bar_dispose (GObject *object)
-{
-  /* ... */
-}
-
-static void
-meta_bar_finalize (GObject *object)
-{
-  /* ... */
-}
-
-static void
-meta_bar_class_init (MetaBarClass *klass)
-{
-  GObjectClass *object_class = G_OBJECT_CLASS (klass);
-  MetaParentClass *parent_class = META_PARENT_CLASS (klass);
-
-  object_class->dispose = meta_bar_dispose;
-  object_class->finalize = meta_bar_finalize;
-
-  parent_class->spawn_unicorn = meta_bar_spawn_unicorn;
-}
-```
-
-### Interface Implementations
-
-When implementing interfaces, two groups of functions are involved: the init
-function, and the overrides.
-
-The interface init function is named after the interface type in snake case,
-followed by the `_iface_init` suffix. For example:
-
-
-```c
-static void meta_foo_iface_init (MetaFooInterface *foo_iface);
-
-G_DEFINE_TYPE_WITH_CODE (MetaBar, meta_bar, G_TYPE_OBJECT,
-                         G_IMPLEMENT_INTERFACE (META_TYPE_FOO,
-                                                meta_foo_iface_init));
-```
-
-Then, when implementing each vfunc of the interface, follow the same pattern
-of the [Overrides](###Overrides) section. Here's an example:
-
-```c
-static void
-meta_bar_do_something (MetaFoo *foo)
-{
-  /* ... */
-}
-
-static void
-meta_foo_iface_init (MetaFooInterface *foo_iface)
-{
-  foo_iface->do_something = meta_bar_do_something;
-}
-```
-
-### Auxiliary Functions
-
-Auxiliary functions are above every other functions to minimize the number of
-function prototypes in the file. These functions often grow when factoring out
-the same code between two or more functions:
-
-```c
-static void
-do_something_on_data (Foo *data,
-                      Bar *bar)
-{
-  /* ... */
-}
-
-static void
-random_function (Foo *foo)
-{
-  do_something_on_data (foo, bar);
-}
-
-static void
-another_random_function (Foo *foo)
-{
-  do_something_on_data (foo, bar);
-}
-```
-
-Sometimes, however, auxiliary functions are created to break down otherwise
-large functions - in this case, it is appropriate to keep these auxiliary
-functions close to the function they are tightly related to.
-
-Auxiliary function names must have a verb in the imperative form, and should
-always perform an action over something. They usually don't have the class
-prefix (`meta_`, `clutter_`, or `cogl_`). For example:
-
-```c
-static void
-do_something_on_data (Foo *data,
-                      Bar *bar)
-{
-  /* ... */
-}
-```
-
-Exceptionally, when converting between types, auxiliary function names may
-have the class prefix to this rule. For example:
-
-```c
-static MetaFoo *
-meta_foo_from_bar (Bar *bar)
-{
-  /* ... */
-}
-```
-
-### Callback Functions
-
-Callback function names should have the name of the action in imperative
-form. They don't have any prefix, but have a `_func` suffix. For example:
-
-```c
-static void
-filter_something_func (Foo      *foo,
-                       Bar      *bar,
-                       gpointer  user_data)
-{
-  /* ... */
-}
-```
-
-### Signal Callbacks
-
-Signal callbacks generally have the signal name. They should be prefixed with
-`on_`, or suffixed with `_cb`, but not both. For example:
-
-```c
-static void
-on_realize (ClutterActor *actor,
-            gpointer      user_data)
-{
-  /* ... */
-}
-
-static void
-destroy_cb (ClutterActor *actor,
-            gpointer      user_data)
-{
-  /* ... */
-}
-```
-
-When the callback is named after the object that generated it, and the signal,
-then passive voice is used. For example:
-
-```c
-static void
-click_action_clicked_cb (ClutterClickAction *click_action,
-                         ClutterActor       *actor,
-                         gpointer            user_data)
-{
-  /* ... */
-}
-```

 To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.

-## Coding style and conventions

-See [HACKING.md](./HACKING.md).
-
-## Git messages
+The coding style used is primarily the GNU flavor of the [GNOME coding
+style](https://developer.gnome.org/programming-guidelines/stable/c-coding-style.html.en)
+with some minor additions such as preferring `stdint.h` types over GLib
+fundamental types, and a soft 80 character line limit. However, in general,
+look at the file you're editing for inspiration.

 Commit messages should follow the [GNOME commit message
 guidelines](https://wiki.gnome.org/Git/CommitMessages). We require an URL
-to either an issue or a merge request in each commit. Try to always prefix
-commit subjects with a relevant topic, such as `compositor:` or
-`clutter/actor:`, and it's always better to write too much in the commit
-message body than too little.
-
-## Default branch

-The default development branch is `main`. If you still have a local
-checkout under the old name, use:
-```sh
-git checkout master
-git branch -m master main
-git fetch
-git branch --unset-upstream
-git branch -u origin/main
-git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main

-/**
- * SECTION:clutter-blur
- * @short_description: Blur textures
- *
- * #ClutterBlur is a moderately fast gaussian blur implementation.
- *
- * # Optimizations
- *
- * There are a number of optimizations in place to make this blur implementation
- * real-time. All in all, the implementation performs best when using large
- * blur-radii that allow downscaling the texture to smaller sizes, at small
- * radii where no downscaling is possible this can easily halve the framerate.
- *
- * ## Multipass
- *
- * It is implemented in 2 passes: vertical and horizontal.
- *
- * ## Downscaling
- *
- * #ClutterBlur uses dynamic downscaling to speed up blurring. Downscaling
- * happens in factors of 2 (the image is downscaled either by 2, 4, 8, 16, …)
- * and depends on the blur radius, the texture size, among others.
- *
- * The texture is drawn into a downscaled framebuffer; the blur passes are
- * applied on the downscaled texture contents; and finally, the blurred
- * contents are drawn
- * upscaled again.
- *
- * ## Hardware Interpolation
- *
- * This blur implementation cuts down the number of sampling operations by
- * exploiting the hardware interpolation that is performed when sampling between
- * pixel boundaries. This technique is described at:
- *
- * http://rastergrid.com/blog/2010/09/efficient-gaussian-blur-with-linear-sampling/
- *
- * ## Incremental gauss-factor calculation
- *
- * The kernel values for the gaussian kernel are computed incrementally instead
- * of running the expensive calculations multiple times inside the blur shader.
- * The implementation is based on the algorithm presented by K. Turkowski in
- * GPU Gems 3, chapter 40:
- *
- * https://developer.nvidia.com/gpugems/GPUGems3/gpugems3_ch40.html
