b72f255c0a Start to reduce dependence on glib
Since we've had several developers from admirable projects say they
would like to use Cogl but would really prefer not to pull in
gobject,gmodule and glib as extra dependencies we are investigating if
we can get to the point where glib is only an optional dependency.
Actually we feel like we only make minimal use of glib anyway, so it may
well be quite straightforward to achieve this.

This adds a --disable-glib configure option that can be used to disable
features that depend on glib.

Actually --disable-glib doesn't strictly disable glib at this point
because it's more helpful if cogl continues to build as we make
incremental progress towards this.

The first use of glib that this patch tackles is the use of
g_return_val_if_fail and g_return_if_fail which have been replaced with
equivalent _COGL_RETURN_VAL_IF_FAIL and _COGL_RETURN_IF_FAIL macros.

e86543cd7d Revert "Do not use "near" and "far" variables"
This reverts commit 3d2564df8f.

Since 01e1260aa the 'near' and 'far' defines are now undef'd on
Windows so we no longer have to remember not to use them in Cogl code.

3d2564df8f Do not use "near" and "far" variables
They collide with existing symbols when compiling on Windows.

07c0b9f89f Add CoglDepthState API
Instead of simply extending the cogl_pipeline_ namespace to add api for
controlling the depth testing state we now break the api out. This adds
a CoglDepthState type that can be stack allocated. The members of the
structure are private but we have the following API to setup the state:

    cogl_depth_state_init
    cogl_depth_state_set_test_enabled
    cogl_depth_state_get_test_enabled
    cogl_depth_state_set_test_function
    cogl_depth_state_get_test_function
    cogl_depth_state_set_writing_enabled
    cogl_depth_state_get_writing_enabled
    cogl_depth_state_set_range
    cogl_depth_state_get_range

This removes the following experimental API which is now superseded:

    cogl_material_set_depth_test_enabled
    cogl_material_get_depth_test_enabled
    cogl_material_set_depth_test_function
    cogl_material_get_depth_test_function
    cogl_material_set_depth_writing_enabled
    cogl_material_get_depth_writing_enabled
    cogl_material_set_depth_range
    cogl_material_get_depth_range

Once a CoglDepthState structure is setup it can be set on a pipeline
using cogl_pipeline_set_depth_state().
