texture properly so if it fails to allocate it. It will then crash

Previously the unit tests were using libdl without directly linking to
it. It looks like this ends up working because one of Cogl's
dependencies ends up pulling adding -ldl via libtool. However in some
configurations it looks like this wasn't happening.
To avoid this problem we can just use GModule to resolve the symbols.
g_module_open is documented to return a handle to the ‘main program’
when NULL is passed as the filename and looking at the code it seems
that this ends up using RTLD_DEFAULT so it will have the same effect.
The in-tree copy of glib already has the code for gmodule so this
shouldn't cause problems for --disable-glib.

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 _cogl_pipeline_update_blend_enable() can sometimes show up quite
high in profiles; instead of calling
_cogl_pipeline_update_blend_enable() whenever we change pipeline state
that may affect blending we now just set a dirty flag and when we flush
a pipeline we check this dirty flag and lazily calculate whether blender
really needs to be enabled if it's set.
Since it turns out we were too optimistic in assuming most GL drivers
would recognize blending with ADD(src,0) is equivalent to disabling
GL_BLEND we now check this case ourselves so we can always explicitly
disable GL_BLEND if we know we don't need blending.
This introduces the idea of an 'unknown_color_alpha' boolean to the
pipeline flush code which is set whenever we can't guarantee that the
color attribute is opaque. For example this is set whenever a user
specifies a color attribute with 4 components when drawing a primitive.
This boolean needs to be cached along with every pipeline because
pipeline::real_blend_enabled depends on this and so we need to also call
_cogl_pipeline_update_blend_enable() if the status of this changes.
Incidentally with this patch we now no longer ever use
_cogl_pipeline_set_blend_enable() internally. For now the internal api
hasn't been removed though since we might want to consider re-purposing
it as a public api since it will now not conflict with our own internal
state tracking and could provide a more convenient way to disable
blending than setting a blend string.

This adds a callback that can be registered with
cogl_onscreen_add_dirty_callback which will get called whenever the
window system determines that the contents of the window is dirty and
needs to be redrawn. Under the two X-based winsys's, this is reported
off the back of the Expose events, under SDL it is reported from
SDL_VIDEOEXPOSE or SDL_WINDOWEVENT_EXPOSED and under Windows from the
WM_PAINT messages. The Wayland winsys doesn't really have the concept
of dirtying the buffer but in order to allow applications to work the
same way on all platforms it will emit the event when the surface is
first shown and whenever it is resized.
There is a private feature flag to specify whether dirty events are
supported. If the winsys does not set this then Cogl will simulate
dirty events by emitting one when the window is first allocated and
when it is resized. The only winsys's that don't set this flag are
things like KMS or the EGL null winsys where there is no windowing
system and showing and hiding the onscreen doesn't really make any
sense. In that case Cogl can assume the buffer will only become dirty
once when it is first allocated.

cogl/cogl-private.h
After discussing with Kristian Høgsberg it seems that the semantics of
wl_egl_window_resize is meant to be that if nothing has been drawn to
the framebuffer since the last swap then the resize will take effect
immediately. Cogl was previously always delaying the call to
wl_egl_window_resize until the next swap. That meant that if you
wanted to resize the surface you would have to call
cogl_wayland_onscreen_resize and then redundantly draw a frame at the
old size so that you can swap to get the resize to occur before
drawing again at the right size. Typically an application would decide
to resize at the start of its paint sequence so it should be able to
just resize immediately.
In current Mesa master it seems that there is a bug which means that
it won't actually delay a resize that is done mid-scene and instead it
will just discard what came before. To get consistent behaviour in
Cogl, the code to delay the call to wl_egl_window_resize is still used
if it determines that the buffer is dirty. There is an existing
_cogl_framebuffer_mark_mid_scene call which was being used to track
when the framebuffer becomes dirty since the last clear. This function
is now also used to track a new flag to track whether something has
been drawn since the last swap. It is called ‘mid_scene’ under the
assumption that this may also be useful for other things later.
cogl_framebuffer_clear has been slightly altered to always call
_cogl_framebuffer_mark_mid_scene even if it determines that it doesn't
need to clear because the framebuffer should still be considered to be
in the middle of a scene. Adding a quad to the journal now also begins
the scene.
This also fixes a potential bug where it looks like pending_dx/dy were
never cleared so they would always be accumulated even after the
resize is flushed.

Previously the WGL winsys was expecting the application to send all
windows messages to Cogl via the cogl_win32_renderer_handle_event
function. When using a GLib main loop we can make this work
transparently to the application with a GSource for the magic
G_WIN32_MSG_HANDLE file descriptor. That causes the GMainLoop to wake
up whenever a message is available.
This patch makes the WGL winsys add that magic value as a source fd.
This will only have any meaning if the application is using glib, but
it shouldn't matter because the cogl_poll_renderer_get_info function

This patch is an API break because by default Cogl will now start
stealing all of the Windows messages. Something like Clutter that wants to handle

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.
