Since we don't generate a mipmap chain for uploaded video frames this
avoids setting the min filter to COGL_PIPELINE_FILTER_LINEAR_MIPMAP_LINEAR.
Since COGL_PIPELINE_FILTER_LINEAR is the default and since it is also
dubious that cogl-basic-video-player is directly manipulating layers
that are conceptually internal to cogl-gst this removes the loop that
updates the filtering for cogl-gst layers.

If the URI argument given on the command line doesn't look like a URI

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.
This introduces the internal idea of texture loaders that track the
state for loading and allocating a texture. This defers a lot more work
until the texture is allocated.
There are several intentions to this change:
- provides a means for extending how textures are allocated without
requiring all the parameters to be supplied in a single _texture_new()
function call.
- allow us to remove the internal_format argument from all
_texture_new() apis since using CoglPixelFormat is bad way of
expressing the internal format constraints because it is too specific.
For now the internal_format arguments haven't actually been removed
but this patch does introduce replacement apis for controlling the
internal format:
cogl_texture_set_components() lets you specify what components your
texture needs when it is allocated.
cogl_texture_set_premultiplied() lets you specify whether a texture
data should be interpreted as premultiplied or not.
- Enable us to support asynchronous texture loading + allocation in the
future.
Of note, the _new_from_data() texture constructors all continue to
allocate textures immediately so that existing code doesn't need to be
adapted to manage the lifetime of the data being uploaded.

This declares the interface types CoglFramebuffer, CoglBuffer,
CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when
including the public cogl.h header so that users don't have to use lots
of C type casts between instance types and interface types.
This also removes all of the COGL_XYZ() type cast macros since they do
nothing more than compile time type casting but it's less readable if
you haven't seen that coding pattern before.
Unlike with gobject based apis that use per-type macros for casting and
performing runtime type checking we instead prefer to do our runtime
type checking internally within the front-end public apis when objects
are passed into Cogl. This greatly reduces the verbosity for users of
the api and may help reduce the chance of excessive runtime type

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

This adds a new function to enable per-vertex point size on a
pipeline. This can be set with
cogl_pipeline_set_per_vertex_point_size(). Once enabled the point size
can be set either by drawing with an attribute named
'cogl_point_size_in' or by writing to the 'cogl_point_size_out'
builtin from a snippet.
There is a feature flag which must be checked for before using
per-vertex point sizes. This will only be set on GL >= 2.0 or on GLES
2.0. GL will only let you set a per-vertex point size from GLSL by
writing to gl_PointSize. This is only available in GL2 and not in the
older GLSL extensions.
The per-vertex point size has its own pipeline state flag so that it
can be part of the state that affects vertex shader generation.
Having to enable the per vertex point size with a separate function is
a bit awkward. Ideally it would work like the color attribute where
you can just set it for every vertex in your primitive with
cogl_pipeline_set_color or set it per-vertex by just using the
attribute. This is harder to get working with the point size because
we need to generate a different vertex shader depending on what
attributes are bound. I think if we wanted to make this work
transparently we would still want to internally have a pipeline
property describing whether the shader was generated with per-vertex
support so that it would work with the shader cache correctly.
Potentially we could make the per-vertex property internal and
automatically make a weak pipeline whenever the attribute is bound.
However we would then also need to automatically detect when an
application is writing to cogl_point_size_out from a snippet.

Since 906e1b5eb535a86 Cogland no longer redraws constantly but instead
only draws once at startup and then again whenever a client attaches a
new buffer. Sometimes however it seems that the first paint will get
lost perhaps because it is sent before the window is fully mapped. As
it was previously not handling expose events it would not paint again
until the first client is connected so there would be a blank window
which looks broken.
This patch makes it handle Expose events when it detects that Cogl is
using an X backend. On other backends it will resort to queuing a
redraw every 16ms as it did before.
Although this is probably a bit overkill for such a small example, it
seems like a good idea to only redraw when we think it's necessary so
that we can be sure that the mechanism works. Handling the expose
events means we can have at least one platform where we can test this.

• When the client attaches a new buffer to a surface it is now added
to a struct contaning pending the state instead of immediately

surface is committed.
• The frame callbacks are now queued in a pending list and only added
to the compositor's main list when the surface is committed. Both
lists are now a wl_list instead of a GQueue because it makes it
easier to remove the callback without knowing which list it is in.
• When the buffer is destroyed for a surface the resource for the
buffer is now sent a release event.
• It now flushes the clients in the prepare for the for the Wayland

• Implements a dummy wl_region interface. The only interfaces that
actually use regions (the opaque and input regions) are ignored but
we need the interface to create a resource.
• Most the of the SHM interface is now implemented directly in
libwayland-server except that it still needs to copy the data to the
subregion of the texture when the damage region is committed.
• The callback list for when a resource is destroyed has been unified
into a generic wl_signal implementation so the signature for the
functions has been changed.

• The wl_buffer struct no longer has a user_data parameter so we can't
attach our own CoglandBuffer data to it. Instead the CoglandSurface
now just keeps track of the wl_buffer directly.
• The Cogland example is now unconditionally built instead of checking
the Wayland version number in the configure script. It looks like
this check was broken anyway because it was checking the version of
the gbm package rather than a Wayland package.

The SDL2 winsys will now set the SDL_WINDOW_RESIZABLE flag on the
window before creating it if the resizable property is set on the
onscreen. Note that there doesn't appear to be a way in SDL to change
the flag later so unlike the other winsyses it will only take affect
if it is set before allocating the framebuffer.
The winsys now registers a callback for SDL events so that it can
report window size changes back to the application.

If we're using the system glib library then we need to make sure not to
include headers under deps/glib otherwise we end up with with
incompatible typedefs that break the build.

This SDL example were unnecessarily including <glib.h> but they don't
actually depend on glib so now they are built even if Cogl is being
built with --disable-glib.
(cherry picked from commit 1d3bce7f68b0a6885c10a29cd9836a3541a1b653)
This commit pushes --disable-glib to the extreme of embedding the par of
glib cogl depends on in tree to be able to generate a DSO that does not
depend on an external glib.
To do so, it:
- keeps a lot of glib's configure.ac in as-glibconfig.m4
- pulls the code cogl depends on and the necessary dependencies
