09e664c349 cogl: Allow setting ARBfp source on a CoglShader
This makes CoglProgram/Shader automatically detect when the user has
given an ARBfp program by checking for "!!ARBfp1.0" at the beginning of
the user's source.

ARBfp local parameters can be set with cogl_program_uniform_float
assuming you pass a @size of 4 (all ARBfp program.local parameters
are vectors of 4 floats).

This doesn't expose ARBfp environment parameters or double precision
local parameters.

5741e28cdc cogl: Adds a COGL_FEATURE_SHADERS_ARBFP feature flag
This adds a public feature flag for ARBfp so developers can determine if
the cogl API supports ARBfp or not.

f781bcec7e material: Add cogl_material_{get,set}_user_program
Previously we had an internal only _cogl_material_set_user_program to
redirect legacy usage of cogl_program_use() through CoglMaterial. This
instead makes the API public because until we implement our planned
"snippet" framework we need a stop-gap solution for using shaders in
Cogl.

The plan is to also support ARBfp with the cogl_program/shader API so
this API will also allow clutter-gst to stop using direct OpenGL calls
that conflict with Cogl's state tracking.

1314d0b1a7 material: chain up in layer_pre_change_notify
A change to a layer is also going to be a change to its owning material
so we have to chain up in _cogl_material_layer_pre_change_notify and
call _cogl_material_pre_change_notify. Previously we were only
considering if the owning material was referenced in the journal but
that ignores that it might also have dependants. We no longer need to
flush the journal directly in layer_pre_change_notify.

8556617546 material: unlink old layer from owner when replacing
In _cogl_material_layer_pre_change_notify when we see that a layer has
dependants and it can't be modified directly then we allocate a new
layer. In this case we also have to link the new layer to its required
owner. If the immutable layer we copied had the same owner though we
weren't unlinking that old layer.

eeac7c5f43 material: fix initialization of sparse properties
In _cogl_material_pre_change_notify we need to identify if it's a sparse
property being changed and if so initialize the state group if the given
material isn't currently the authority for it.

Previously we were unconditionally calling
_cogl_material_initialize_state which would e.g. NULL the layer
differences list of a material each time a layer change was notified.

It would also call _cogl_material_initialize_state for non-sparse
properties which should always be valid at this point so the function
has been renamed to _cogl_material_initialize_sparse_state to make this
clearer with a corresponding g_return_if_fail check.

d489832688 material: fix copying of material layer differences
This fixes how we copy layer differences in
_cogl_material_copy_layer_differences.

We were making a redundant g_list_copy of the src differences and then
iterating the src list calling _cogl_material_add_layer_difference for
each entry which would double the list length, but the initial copy
directly referenced the original layers which wasn't correct.

Also we were initializing dest->n_layers before copying the layer
differences but the act of copying the differences will re-initialize
n_layers to 0 when adding the first layer_difference since it will
trigger a layer_pre_change_notify and since the dest material isn't yet
a STATE_LAYERS authority the state group is initialized before allowing
the change.

0e2880b067 material: don't dereference layer->texture directly
In _cogl_material_texture_storage_change_notify we were potentially
dereferencing layer->texture without checking first that it is the
authority of texture state. We now use
_cogl_material_layer_get_texture() instead.

9c46cb7f21 material: Improve the dot file debugging code
This improve the dot file output available when calling
_cogl_debug_dump_materials_dot_file. The material graph now directly
points into the layer graph and the layers now show the texture unit
index.

1943b8e544 glx: Depend on libdrm
DRM is available on more platforms than Linux (e.g. kFreeBSD), but
Clutter currently FTBFS there because of not being an alternative to
the __linux__ code (where it should be HAVE_DRM).

Instead of copying the DRM data structures, we should use libdrm when
falling back to directly requesting to wait for the vblank.

d07a525ecc text: Do not set the markup unconditionally
When setting :use-markup we always pass the contents of the Text actor
to clutter_text_set_markup_internal(); if string contains any markup,
this ends up being parsed and used - even when :use-markup is set to
FALSE.

fcbfd4ec34 cogl-material: Unref the texture when reverting authority
When the texture is set on a layer so that it is back to the parent's
texture it would clear the texture change flag but it wouldn't unref
the texture. The free function for a material layer does not unref the
texture if the change flag is cleared so the texture would end up
leaking. This happens for ClutterTexture because it disposes the
texture by setting layer 0 of the material to COGL_INVALID_HANDLE
which ends up the same as the default material.

8ac3cb29ea material: only deference layer->texture for authority

069266f3ed layout-manager: Freeze ::layout-changed when creating LayoutMeta
LayoutMeta instances are created lazily. If an actor is added to a
container with a layout manager then the first time the layout manager
might be creating the LayoutMeta instance could be during the allocation
cycle caused by calling clutter_actor_show(). When a LayoutMeta is
instantiated for the first time, a list of properties can be set - and
this might lead to the emission of the ::layout-changed signal. The
signal is, most typically, going to cause a relayout to be queued, and a
warning will be printed on the terminal.

We should freeze the emission of the ::layout-changed signal during the
creation of the LayoutMeta instances, and thaw it after that.

315965290b texture: Update the request mode depending on the size
If a Texture has been set to:

  • keep its size synchronized with the image data
  • maintain the aspect ratio of the image data

then it should also change its request mode depending on the orientation
of the image data, so that layout managers have a fighting chance of
sizing it correctly.

8326ea26f8 osx: Fixed stage resize policy
Added initialization of minimum window size property on Cocoa
side. This property works when user change window size by mouse
dragging. But when size is changed by clutter_actor_set_size this
property will not help and was added another check in
clutter_stage_osx_resize. Also osx_get_geometry was refactoried
because it returns incorrect values in many cases but now size is
saved in [Window reshape] in requisition_width/height and this value
will be returned in any case to frontend.
