af7398788a remove internal_format and redundant error arguments
Texture allocation is now consistently handled lazily such that the
internal format can now be controlled using
cogl_texture_set_components() and cogl_texture_set_premultiplied()
before allocating the texture with cogl_texture_allocate(). This means
that the internal_format arguments to texture constructors are now
redundant and since most of the texture constructors now can't ever fail
the error arguments are also redundant. This now means we no longer
use CoglPixelFormat in the public api for describing the internal format
of textures which had been bad solution originally due to how specific
CoglPixelFormat is which is missleading when we don't support such
explicit control over the internal format.

Note: there are numerous API changes for functions currently marked
as 'unstable' which we don't think are in use by anyone depending on
a stable 1.x api. Compared to the original patch though this avoids
changing the cogl_texture_rectangle_new_with_size() api which we know
is used by Mutter.

e9f721216e Add _primitive_draw to replace _framebuffer_draw_primitive
When splitting out the CoglPath api we saw that we would be left with
inconsistent drawing apis if the drawing apis in core Cogl were lumped
into the cogl_framebuffer_ api considering other Cogl sub-libraries or
that others will want to create higher level drawing apis outside of
Cogl but can't use the same namespace.

So that we can aim for a more consistent style this adds a
cogl_primitive_draw() api, comparable to cogl_path_fill() or
cogl_pango_show_layout() that's intended to replace
cogl_framebuffer_draw_primitive()

Note: the attribute and rectangle drawing apis are still in the
cogl_framebuffer_ namespace and this might potentially change but in
these cases there is no single object representing the thing being drawn
so it seems a more reasonable they they live in the framebuffer
namespace for now.

Note: the cogl_framebuffer_draw_primitive() api isn't removed by this
patch so it can more conveniently be cherry picked to the 1.16 branch so
we can mark it deprecated for a short while. Even though it's marked as
experimental api we know that there are people using the api so we'd
like to give them a chance to switch to the new api.

937337993d tests: stop using cogl-auto-texture apis
The plan is to remove the cogl-auto-texture apis since they hide a bit
too much from developers but currently the conformance tests depend on
these apis in numerous places.

For the conformance tests it makes some sense to continue using high
level texture apis similar to the auto-texture apis since we may want
to make broad variations to how textures are allocated as part of the
testing running if that might help exercise more code paths.

This patch copies much of the auto-texture functionality into some
slightly more special purpose utilities in test-utils.c/h. Minor changes
include being constrained to the public Cogl api and they also don't
let you catch CoglErrors and just assume they should abort on error.

54735dec84 Switch use of primitive glib types to c99 equivalents
The coding style has for a long time said to avoid using redundant glib
data types such as gint or gchar etc because we feel that they make the
code look unnecessarily foreign to developers coming from outside of the
Gnome developer community.

Note: When we tried to find the historical rationale for the types we
just found that they were apparently only added for consistent syntax
highlighting which didn't seem that compelling.

Up until now we have been continuing to use some of the platform
specific type such as gint{8,16,32,64} and gsize but this patch switches
us over to using the standard c99 equivalents instead so we can further
ensure that our code looks familiar to the widest range of C developers
who might potentially contribute to Cogl.

So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this
switches all Cogl code to instead use the int{8,16,32,64}_t and
uint{8,16,32,64}_t c99 types instead.

Instead of gsize we now use size_t

For now we are not going to use the c99 _Bool type and instead we have
introduced a new CoglBool type to use instead of gboolean.

3881fd3259 Adds cogl_framebuffer_draw_[*_]rectangle functions
This adds experimental 2.0 api replacements for the cogl_rectangle[_*]
functions that don't depend on having a current pipeline set on the
context via cogl_{set,push}_source() or having a current framebuffer set
on the context via cogl_push_framebuffer(). The aim for 2.0 is to switch
away from having a statefull context that affects drawing to having
framebuffer drawing apis that are explicitly passed a framebuffer and
pipeline.

To test this change several of the conformance tests were updated to use
this api instead of cogl_rectangle and
cogl_rectangle_with_texture_coords. Since it's quite laborious going
through all of the conformance tests the opportunity was taken to make
other clean ups in the conformance tests to replace other uses of
1.x api with experimental 2.0 api so long as that didn't affect what was
being tested.

bbcbece6c9 tests: Improve thoroughness and reporting of make test
This patch reworks our conformance testing framework because it seems
that glib's gtesting framework isn't really well suited to our use case.
For example we weren't able to test windows builds given the way we
were using it and also for each test we'd like to repeat the test
with several different environments so we can test important driver and
feature combinations.

This patch instead switches away to a simplified but custom approach for
running our unit tests. We hope that having a more bespoke setup will
enable us to easily extend it to focus on the details important to us.

Notable changes with this new approach are:

We can now run 'make test' for our mingw windows builds.

We've got rid of all the test-*report* make rules and we're just left
with 'make test'

'make test' now runs each test several times with different driver and
feature combinations checking the result for each run. 'make test' will
then output a concise table of all of the results.

The combinations tested are:
- OpenGL Fixed Function
- OpenGL ARBfp
- OpenGL GLSL
- OpenGL No NPOT texture support
- OpenGLES 2.0
- OpenGLES 2.0 No NPOT texture support

785e6375eb Adds a context arg to cogl_pipeline_new()
As we move towards Cogl 2.0 we are aiming to remove the need for a
default global CoglContext and so everything should be explicitly
related to a context somehow. CoglPipelines are top level objects and
so this patch adds a context argument to cogl_pipeline_new().

92c3063014 framebuffer: Add cogl_framebuffer draw methods
This adds cogl_framebuffer_ apis for drawing attributes and primitives
that replace corresponding apis that depend on the default CoglContext.
This is part of the on going effort to adapt the Cogl api so it no
longer depends on a global context variable.

All the new drawing functions also take an explicit pipeline argument
since we are also aiming to avoid being a stateful api like Cairo and
OpenGL. Being stateless makes it easier for orthogonal components to
share access to the GPU. Being stateless should also minimize any
impedance miss-match for those wanting to build higher level stateless
apis on top of Cogl.

Note: none of the legacy, global state options such as
cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or
cogl_program_use() are supported by these new drawing apis and if set
will simply be silently ignored.

b5a7657076 Starts porting Cogl conformance tests from Clutter
This makes a start on porting the Cogl conformance tests that currently
still live in the Clutter repository to be standalone Cogl tests that no
longer require a ClutterStage.

The main thing is that this commit brings in is the basic testing
infrastructure we need, so now we can port more and more tests
incrementally.

Since the test suite wants a way to synchronize X requests/replies and
we can't simply call XSynchronize in the test-utils code before we know
if we are really running on X this adds a check for an environment
variable named "COGL_X11_SYNC" in cogl-xlib-renderer.c and if it's set
it forces XSynchronize (dpy, TRUE) to be called.

By default the conformance tests are run off screen. This makes the
tests run much faster and they also don't interfere with other work you
may want to do by constantly stealing focus. CoglOnscreen framebuffers
obviously don't get tested this way so it's important that the tests
also get run on screen every once in a while, especially if changes are
being made to CoglFramebuffer related code.  On screen testing can be
enabled by setting COGL_TEST_ONSCREEN=1 in your environment.
