This allows us to catch the use of undefined macros (that default to 0)

Some variables (notably multiline ones) are not really supposed to be
substituted by automake. Let's take COGL_DEFINES for instance, you get:
COGL_DEFINES =
#define COGL_HAS_GLIB_SUPPORT
#define COGL_HAS_GTYPE_SUPPORT
#define COGL_HAS_GL
#define CLUTTER_COGL_HAS_GL
#define COGL_HAS_GLX_SUPPORT
#define COGL_HAS_SDL
...
This only works because the '#' character makes it look like a comment
and COGL_DEFINES becomes an empty variable
Automake allows to exclude variables from the list of substitutions,
let's use it for those two.

COGL_HAS_* and COGL_ENABLE_DEBUG are either defined in config.h or not.
So let's test against this, not against their truth value, this allow us

Cogl always needs to have the context bound to something so that it
can freely create resources such as textures even if there is no
current window. When the currently bound SDLWindow is destroyed, SDL
apparently explicitly unbinds the GL context. If something then later
for example tries to create a texture Cogl would start getting GL
errors and fail. To fix this the SDL winsys now just binds the dummy
window before deiniting the currently bound onscreen.

We have found several times now when writing code using Cogl that it
would really help if Cogl's matrix stack api was public as a utility
api. In Rig for example we want to avoid redundant arithmetic when
deriving the matrices of entities used to render and we aren't able
to simply use the framebuffer's matrix stack to achieve this. Also when
implementing cairo-cogl we found that it would be really useful if we
could have a matrix stack utility api.

At times there can be huge numbers of CoglMatrixEntry structures
allocated if they are being used to track the transform of many drawing
commands or objects in a scenegraph. Therefore the size of a
CoglMatrixEntry should be kept as small as possible both to help reduce
the memory usage of applications but also to improve cache usage since
matrix stack manipulations are performance critical at times.
This reduces the size of CoglMatrixEntry structures for non-debug builds
by removing the composite_gets counter used to sanity check how often
the transform for an entry is resolved.

This moves the parent pointer member to the top of the CoglMatrixEntry
structure since it will lead to wasted padding when we build for 64bit
cpus.
(cherry picked from commit 42b4750070286a6404b103d8a827a46efb6b344c)
When unrefing a CoglMatrixEntry we walk up the ancestry unrefing and
freeing entries until we find an entry that doesn't need to be freed.
The problem fixed by this patch was that we didn't dereference the
parent member of each entry until after the entry was freed and so there
was the potential for reading a junk parent pointer back.

It is considered an error to pass a NULL data pointer to

Both the texture drivers weren't handling errors correctly when a
CoglPixelBuffer was used to set the contents of an entire texture.
This was causing it to hit an assertion failure in the pixel buffer

test-pixel-buffer previously had two tests, one to check filling the
pixel buffer by mapping it and another to fill it by just setting the
data. These tests were set up in a kind of confusing way where it
would try to paint both steps and then validate them together using
colors looked up from a table. This patch separates out the two tests
and gets rid of the tables which hopefully makes them a bit easier to
follow.
The contents of the bitmap are now set to an image with has a
different colour for each of its four quadrants instead of just a
single colour in the hope that this will be a bit more of an extensive
test.
The old code had a third test that was commented out. This test has
been removed.
The textures are now created using cogl_texture_2d_new_* which means
they won't be in the atlas. This exposes a bug where setting the
entire contents of the texture won't handle errors properly and it
will hit an assertion. The previous code using the atlas would end up
only setting a sub-region of the larger atlas texture so the bug
wouldn't be hit. To make sure we still test this code path there is
now a third test which explicitly sets a sub-region of the texture
using the bitmap.

cogl_texture_set_region() and cogl_texture_set_region_from_bitmap() now
have a level argument so image data can be uploaded to a specific mipmap
level.
The prototype for cogl_texture_set_region was also updated to simplify

be consistent with cogl_texture_set_region with the source related
arguments listed first followed by the destination arguments.

This updates the Cogl Pango api to no longer require a default context
and also cleans up the public api a bit.
The CoglPangoRenderer type has been made private to be
consistent with other pango backends where the renderer is merely an
implementation detail.
The drawing apis such as cogl_pango_render_layout where made more
consistent with other pango backend apis so we now have replacements
like cogl_pango_show_layout().

The _cogl_propagate_error() function takes ownership of the incoming
error pointer so there's no need to allocate a new error when passing
it on. The errors can potentially be passed up from a number of layers
so it seems worthwhile to avoid the allocation.
The _cogl_propagate_gerror() function was previously using
_cogl_propagate_error(). Presumably this would not have worked because
that function would try to free the error from glib using
cogl_error_free but that would use the wrong free function and thus
the wrong slice allocator. The GError propagating function is only
used when gdk-pixbuf is enabled which now requires glib support anyway
so we can just avoid defining the function when compiling without
glib.
