a871ac669f test-shader: guard GLES2 specific changes with COGL_HAS_GLES2
Previously we were using an internal only HAVE_COGL_GLES2 define to
guard GLES 2 specific changes so for instance the precision modifiers
weren't being emitted in the shader source.

60cad4bf0b gles2: don't disable clip planes for GLES2
GLES2 doesn't provide user clip planes (you would have to use a vertex +
fragment shader to achieve the same kind of result) so we make sure not
to call glEnable/Disable with any of the GL_CLIP_PLANE0..3 defines.

00bb189e71 material: fix a typo in _cogl_material_journal_unref
The function had a line like:

CoglMaterial *material =
    material = _cogl_material_pointer_from_handle (material_handle);

where the duplicate "material =" wasn't intended, so this patch removes
it.

f3adc600fc backend: Undeprecated clutter_backend_get_resolution()
Since the Settings:font-dpi property is exposed as 1024 * real_dpi in
order to make the setting as neutral as possible (and allow XSETTINGS
to use it natively) we need a simple API returning the DPI using a
floating point value.

e4e6a6dfe5 configure.ac only explicitly add -lGL if no pkgconfig file

happens that this only ever gets used with the eglnative backend.

cd82b704e9 egl: support creating OpenGL contexts
Right before we create the EGL context, we check if we were built with
OpenGL or OpenGLES support and it was OpenGL then we call eglBindAPI
(EGL_OPENGL_API); This also explicitly requests a EGL_RENDERABLE_TYPE
supporting the EGL_OPENGL_BIT.

This will let us add a new ./configure flavour that combines OpenGL and
EGL instead of OpenGL and GLX.

53bf95466b build: Adds a new opengl-egl-xlib build flavour
With this patch if you ./configure clutter using
--with-flavour=opengl-egl-xlib then it will use EGL + OpenGL instead of
the default GLX and OpenGL.

These days upstream driver work is more focused on improving EGL than it
is GLX so likewise we want to make sure Clutter has good support for
EGL.

bf9d5f3949 build: distinguish CLUTTER_WINSYS and CLUTTER_SONAME_INFIX
This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.

For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.

4bd44738fd configure.ac: avoid some duplication
When we check the flavour we now just set boolean variables for the
following things:

SUPPORT_X11=1
SUPPORT_XLIB=1
SUPPORT_GLX=1
SUPPORT_EGL=1
SUPPORT_EGL_POWERVR_X11=1
SUPPORT_EGL_POWERVR_NULL=1

This lets us avoid some duplication and also some error prone tests for
lists of flavours used, for example, to determine when we need to check
for x libraries.

25ed304567 configure.ac: distinguish CLUTTER_FLAVOUR and CLUTTER_WINSYS
It's desirable to have a separation between the "flavour" and the
"winsys". The flavour is a concept internal to the configure script and
is a convenient name to represent the users choice of window system,
opengl driver and input backend. The CLUTTER_WINSYS currently defines
the subdirectory under clutter/ that should be compiled to handle the
window system and input.

With a separation we could add a flavour with no correspondence to which
clutter/subdirectory needs to be built.

c3e43a7e47 configure.ac: move the special handling of the fruity flavour
After checking the flavour option the user gives we were checking for
the fruity flavour to override the glesversion. Now that the glsl
checking has been moved this can instead just wait until the AS_CASE
that handles all the flavour configuration.

e3293abcd4 configure.ac: move gles checks after the flavour checks
The flavour AS_CASE should define whether a flavour uses the gl or gles
COGL_DRIVER and so we shouldn't need to have an expanding list of
tests to gate when we check for a gles driver because if we move the
checks for gles after the flavour checks we can just look at
$COGL_DRIVER.

c151fa2efd configure.ac: don't have so many XYX_{LIBS,CFLAGS} vars
This removes EGL_{LIBS,CFLAGS}, GLX_{LIBS,CFLAGS}, OSX_{LIBS,CFLAGS},
WIN32_{LIBS,CFLAGS}, and GLES_{LIBS,CFLAGS} and instead we just append
to FLAVOUR_{LIBS,CFLAGS}.

This makes more of the file relocatable because there were previously
dependencies on the order that some variables were setup in.

e2dcd7e852 clutter-stage: Use g_array_free instead of g_array_unref
g_array_unref was only added in GLib 2.22 so we should really update
the requirements in the configure script if we want to use that
function. However the array doesn't appear to have any extra reference
taken on it anywhere so it should be safe to use g_array_free instead.

5a73e20a15 cogl-context: Use the function pointer for glActiveUnit
Under WGL, any functions that were defined after GL 1.1 are not
directly exported in the DLL so we need to reference them via the

9cc9033347 cogl-material: Don't use the symbol 'near'
The window headers contain the line

 #define near

so it's not possible to use the symbol 'near' in code that's portable
to Windows. This replaces it with 'near_val'.

I think the define is meant to improve compatibility with code written
for Windows 3.1 where near would be a keyword to make it a smaller
pointer size.

0411ba7d32 actor: Parse actions, constraints and effects members
ClutterActor should allow attaching actions, constraints and effects
just like it allows behaviours, e.g.:

  {
    ...
    "constraints" : [
      {
        "type" : "ClutterAlignConstraint",
        "source" : "stage",
        "align-axis" : "x-axis",
        "factor" : 0.5
      },
      {
        "type" : "ClutterAlignConstraint",
        "source" : "stage",
        "align-axis" : "y-axis",
        "factor" : 0.5
      }
    ],
    ...
  }

or:

  {
    ...
    "actions" : [
      {
        "type" : "ClutterDragAction",
        "signals" : [
          { "name" : "drag-end", "handler" : "on_drag_end" }
        ]
      }
    ],
    ...
  }

In order to do so, we use the Scriptable interface implementation and
add three new custom properties accepting an array; then we parse each
member of the array as a new object.

a75c02a5d6 constraints: Allow Align and Bind sources to be NULL
Since constructing AlignConstraint and BindConstraint instances could be
deferred (think ClutterScript) we need to make their :source properties
setters accept NULL. This does not break the constraints because they
need to handle that condition in case they actor to which they are
applied is destroyed and somebody is holding a reference on them anyway.

a4dbcf0c32 script-parser: Expose extracting the id from a node
The get_id_from_node() internal function should be exposed inside
Clutter (as a private function) because it can be useful to other

pointless to re-implement it.

2d99f77e3b cairo-texture: Disable :sync-size
The :sync-size property of ClutterTexture should be set to FALSE by
default by ClutterCairoTexture. The preferred size of the
ClutterCairoTexture is already the size of the internal Cairo surface,
and we override the preferred width/height getters to that effect.

The :sync-size property is also responsible of changing the size of
the Texture actor when changing the texture handle - but since we
encourage that to happen during the CairoTexture allocation, we get a
queue_relayout() invocation (and a warning) when we change the size
of the Cairo image surface.

Since GObject doesn't make it easy to override the default value of the
:sync-size property in sub-classes, we should simply call the setter
function during the ClutterCairoTexture instance initialization.

We should also change one of the interactive tests using a CairoTexture
to rebuild the contents of the actor in response to an allocation.

56315d92bd stage-glx: Never promote clipped redraws to full redraws.
When clipped redraws were first supported in Clutter a heuristic was
added to promote tall clipped redraws into full redraws due to a concern
that using glXCopySubBuffer for tall rectangles would block the GPU for
too long waiting for the vtrace to be in a suitable position so that
tearing isn't seen. We've so far been unable to measure any impact from
this blocking even with full height windows so we are removing the
arbitrary threshold of 300px that was originally "plucked out of thin
air".
