In the future if we want to annotate matrices with internal flags, and add
caching of the inverse matrix then we need to ensure that all matrix
modifications are done by cogl_matrix API so we'd know when to dirty the
cache or update the flags.
This just adds documentation to that effect, and assuming the most likley
case where someone would try and directly write to matrix members would
probably be to load a constant matrix other than the identity matrix; I
renamed cogl_matrix_init_from_gl_matrix to cogl_matrix_init_from_array to
make it seem more general purpose.
Since the CoglMatrix type was added for supporting texture matrices recently
it made sense to be consistent accross the Cogl API and use the Cogl type
over the GL style GLfloat m[16] arrays.
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.
It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.
Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.
This tries to make a number of files more comparable with the intention of
moving some code into cogl/common/
Files normalized:
cogl.c
cogl-context.c
cogl-context.h
cogl-texture.c
This makes it consistent with cogl_rectangle_with_{multi,}texture_coords.
Notably the reason cogl_rectangle_with_{multi,}texture_coords wasn't changed
instead is that the former approach lets you describe back facing rectangles.
(though technically you could pass negative width/height values to achieve
this; it doesn't seem as neat.)
This updates cogl/gles in line with the integration of CoglMaterial throughout
Cogl that has been done for cogl/gl.
Note: This is still buggy, but at least it builds again and test-actors works.
Some GLES2 specific changes were made, but these haven't been tested yet.
This changes all GLES code to use the OpenGL function names instead of
the cogl_wrap_* names. For GLES2 we now define the OpenGL name to point
to the wrapper, as opposed to defining the wrapper to point to the
OpenGL name for GLES1.
I've also done a quick pass through gl/cogl.c and gles/cogl.c to make
them more easily comparable. (most of the code is now identical)
The GL blend function and alpha function are now controlled by the material
code, and even internally Cogl should now be using the material API when
it needs control of these.
To deal with all the corner cases that couldn't be scripted a number of patches
were written for the remaining 10% of the effort.
Note: again no API changes were made in Clutter, only in Cogl.
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.
Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
so that applications may still take advantage of fixed point if they
desire for certain optimisations where lower precision may be acceptable.
Note: no API changes were made in Clutter, only in Cogl.
Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.
- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.
- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.
- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.
* clutter/cogl/cogl-path.h:
* clutter/cogl/common/cogl-primitives.c:
* clutter/cogl/common/cogl-primitives.h:
* clutter/cogl/gl/cogl-primitives.c:
* clutter/cogl/gles/cogl-primitives.c: Changed the semantics of
cogl_path_move_to. Previously this always started a new path but
now it instead starts a new disjoint sub path. The path isn't
cleared until you call either cogl_path_stroke, cogl_path_fill or
cogl_path_new. There are also cogl_path_stroke_preserve and
cogl_path_fill_preserve functions.
* clutter/cogl/gl/cogl-context.c:
* clutter/cogl/gl/cogl-context.h:
* clutter/cogl/gles/cogl-context.c:

to a GArray.
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gles/cogl-texture.c: Call cogl_clip_ensure
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
stack code quite a bit to make it more maintainable. Previously
whenever you added a new clip it would go through a separate route
to immediately intersect with the current clip and when you
removed it again it would immediately rebuild the entire clip. Now
when you add or remove a clip it doesn't do anything immediately
but just sets a dirty flag instead.
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c: Taken away the code to intersect
stencil clips when there is exactly one stencil bit. It won't work
with path clips and I don't know of any platform that doesn't have
eight or zero stencil bits. It needs at least three bits to
intersect a path with an existing clip. cogl_features_init now
just decides you don't have a stencil buffer at all if you have
less than three bits.
* clutter/cogl/cogl.h.in: New functions and documentation.
* tests/interactive/test-clip.c: Replaced with a different test
that lets you add and remove clips. The three different mouse
buttons add clips in different shapes. This makes it easier to
test multiple levels of clipping.

cogl_path_stroke_preserve when using the same path again.

* clutter/cogl/cogl-path.h:
* clutter/cogl/cogl-types.h:
* clutter/cogl/common/cogl-color.c: Deprecated cogl_color()
in favour of cogl_set_source_color() and friends; store the
CoglColor components as unsigned bytes instead of fixed point
normalized values; add functions for allocating, copying and
freeing CoglColor, for use of language bindings.
* clutter/cogl/cogl.h.in:

an header file containing the deprecation symbols similar

CoglColor whenever it is possible.
* clutter/cogl/common/cogl-fixed.c (cogl_fixed_sin)
(cogl_angle_sin, cogl_angle_tan, cogl_fixed_sqrt): Replaced uses
of 1 + ~x with just -x which is equivalent and easier to
understand.
Bug 1211 - Drop ClutterFeatureFlags usage from COGL
* clutter/cogl/cogl.h.in:
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c: Do not use ClutterFeatureFlags
when CoglFeatureFlags will do. This removes the last usage
of Clutter API inside COGL.

* clutter/cogl/cogl.h.in:
* clutter/cogl/common/Makefile.am:
* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled
after the ClutterFixed. The CoglFixed API supercedes the ClutterFixed
one and avoids the dependency of COGL on Clutter's own API.

maintain a stack of clipping rectangles.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gl/cogl.c: The cogl_clip_set and unset functions
have moved into cogl-clip-stack.c which calls back to cogl.c to
set the actual rectangles. Multiple clip rectangles are combined
by merging the stencil buffers.
* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes):
* clutter/cogl/gl/cogl-primitives.c (_cogl_path_fill_nodes): Merge

now stored in a separate struct so they can be stored for
application program objects as well.

separate files.
(_cogl_features_init): Report support for the shaders feature on
GLES 2

* clutter/cogl/gles/cogl-shader.c:
* clutter/cogl/gles/cogl-program.h:
* clutter/cogl/gles/cogl-program.c: Separate files to handle
shaders on programs on GLES. If version 1.1 is being used then the
stub functions which all fail are still used.
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_gles2_wrapper_init, cogl_gles2_wrapper_bind_attributes),
(cogl_gles2_wrapper_get_uniforms): Move the uniforms and attribute
bindings into a separate function so they can be used to bind on

glGetIntegerv
* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes): Use
_cogl_features_available to check for the stencil buffer instead
of an #ifdef. The stencil buffer is available in the default
profile for the GLES 2 simulator.
* clutter/eglx/clutter-stage-egl.h:
* clutter/eglx/clutter-egl-headers.h:
* clutter/eglx/clutter-backend-egl.h:
* clutter/eglx/Makefile.am: Include the GLES and EGL headers via

depending on whether the GLES 2 wrapper is being used.
* configure.ac: Added an automake conditional for whether the GLES
2 wrapper should be used.
* clutter/eglx/clutter-stage-egl.c (clutter_stage_egl_realize):
Remove the call to glGetIntegerv to get the max texture size. It

shaders into a C string.
* clutter/cogl/gles/cogl-gles2-wrapper.h:

for the state of the GLES 2 wrapper.
* clutter/cogl/gles/cogl-texture.c:

* clutter/cogl/gles/cogl.c: Use wrapped versions of the GL
functions where neccessary.
* clutter/cogl/gles/Makefile.am: Add sources for the GLES 2
wrapper and an extra build step to put the GLSL files into a C
string whenever the files change.
* clutter/cogl/gles/cogl.c (error_string): Rename to
_cogl_error_string and remove the static scoping so that it can be
called in cogl-texture etc.
* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):

(_cogl_texture_quad_hw, cogl_texture_polygon): Remove GE(*)
wrapper around calls in the middle of a glBegin/glEnd pair which
otherwise always generate an error because glGetError can only be
called outside of the pair.
* clutter/cogl/gl/cogl-internal.h: Include stdio.h when definig
COGL_DEBUG and declare a prototype for _cogl_error_string.
* clutter/cogl/gles/cogl-internal.h: Match GE(*) macro to GL
version.
cogl_blend_func caches blending setup much like cogl_enable
does with the enable flags. This separates blending factors
setup from the enable/disable operation in preparation of
the texture image retrieval fix for alpha channel on GLES.
(cogl_enable:) Does not modify blending factors anymore.
* clutter/cogl/gl(es)/cogl-context.h: CoglContext holds two
new variables to cache blending src and dst factors.
* clutter/cogl/gl(es)/cogl-context.c:
(cogl_create_context:) Initialize blending factors.
* clutter/cogl/gles/cogl-texture.c:
(cogl_texture_download_from_gl:) Set blending factors to
CGL_ONE, CGL_ZERO which fixes the slighlty improper behavior
where source colour was actually multiplied with its alpha
value in the result (not noticable on current tests).

New files to hold the shader and program functions.
* clutter/cogl/gl/cogl.c: Removed shader and program functions.
* clutter/cogl/common/cogl-handle.h: New header to define
COGL_HANDLE_DEFINE which helps build functions to create
reference-counted handles. This reduces the amount of duplicated
code.
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE
from cogl-handle.h to avoid duplicating some of the common code.

(libclutter_cogl_common_la_SOURCES): Added cogl-handle.h
* clutter/cogl/gles/cogl.c:
* clutter/cogl/cogl.h.in: Programs and shaders are now wrapped in
CoglHandles instead of COGLhandles. cogl_program_destroy and
cogl_shader_destroy is now replaced with cogl_program_unref and
cogl_shader_unref. cogl_program_ref and cogl_shader_ref are also
added.
* clutter/clutter-shader.c: Converted to use CoglHandles for the
programs and shaders instead of COGLhandles.
* cogl/cogl-sections.txt: Added cogl_shader_ref,
cogl_shader_unref, cogl_is_shader, cogl_program_ref,
cogl_program_unref, cogl_is_program and cogl_is_offscreen.

Modify to take advantage of new show-on-set-parent functionality.
* clutter/cogl/cogl.h:
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c:
Disable the depth test and buffer as has some strange side
effects, mainly on x/y axis rotation with multiple layers at
same depth (eg rotating text on a bg has very strange
effect). Seems no clean 100% effective way to fix without other
odd issues.. So for now move to application to handle and add
cogl_enable_depth_test() as for custom actors (i.e groups) to
enable if need be.

* tests/Makefile.am:
* tests/test.fbo.c:
Add initial support for FBO's in Clutter (OpenGL only so far).
See new clutter_texture_new_from_actor()
Initial implementation, needs work.
* clutter/x11/clutter-stage-x11.c:
(clutter_stage_x11_set_cursor_visible):
Fall back to again not relying on xfixes to hide cursor. *sigh*
* clutter/clutter-deprecated.h:
Add clutter_group_find_child_by_id
* clutter/cogl/cogl.h: Rename COGLhandleARB to COGLhandle.
* clutter/cogl/gl/cogl-defines.h.in:
* clutter/cogl/gl/cogl.c: Update GL implementation of COGL.
* clutter/cogl/gles/cogl-defines.h:
* clutter/cogl/gles/cogl.c: Update GLES implementation of COGL.
* clutter/clutter-shader.c: Fix ClutterShader to use the new
COGLhandle type instead of COGLhandlerARB.
Define COGLhandleARB. (patch by Johan Bilien)
* clutter/cogl/gles/cogl-defines.h: Define COGLhandleARB on
GLES as well (using GLuint)
* clutter/cogl/gles/cogl.c: Use COGLhandleARB.
* clutter/cogl/cogl.h: Update cogl_clip_set() to accept the
clip components as ClutterFixed values
* clutter/cogl/gl/cogl.c (cogl_clip_set): Update the GL implementation
of cogl_clip_set()
* clutter/cogl/gles/cogl.c:
(cogl_rectangle_internal): Provide an internal, inlined rectangle
drawing function using fixed point values, to be shared by
cogl_clip_set() and cogl_rectangle()
(cogl_clip_set), (cogl_rectangle): Update the GLES implementation
of cogl_clip_set() and cogl_rectangle() to use the new internal
rectangle drawing function
* clutter/clutter-actor.c: Make the clip an array of ClutterUnit
values instead of pixel-based; this allows higher precision and
device independence
(_clutter_actor_apply_modelview_transform): Pass the clip
components converting from units to fixed point values, using
the new cogl_clip_set() signature
(clutter_actor_get_property), (clutter_actor_set_clip),
(clutter_actor_get_clip): Update the accessors of the clip
property
* clutter/cogl/cogl.h: Add cogl_fog_set() abstracting the
glFog() functions and enabling the GL_FOG flag.
* clutter/cogl/gl/cogl.c: Add GL implementation of cogl_fog_set().
* clutter/cogl/gles/cogl.c: Add GL/ES implementation of
cogl_fog_set().
* clutter.symbols: Add new symbols.
* clutter/clutter-stage.h: Add API to enable depth cueing on
the stage using a linear GL fog, and to set the parameters
for it (#637).
* clutter/clutter-stage.c (clutter_stage_paint): Enable the
GL fog if the ClutterStage:use-fog property is true.
* tests/test-depth.c: Test the new stage API.

Create a new X11 backend class of which EGL and GLX 'real' backends
then subclass. Effectively shares all X11 code between both backends
avoids code duplication and brings many missing features to EGL X
backend. Requires some cleanup and testing. (#518)
* clutter/cogl/gles/cogl.c: (cogl_color):
Add define to use color4ub only if configure finds it.
If not fall back to old code.
* configure.ac:
Drop support for vincent checks.
Drop sdles backend.
Specifically check for color4ub call.
* clutter/cogl/gles/cogl.c: (cogl_color):
Switch over to using glColor4ub in the GLES backend. It's available in
the header file but missing in the reference manual.
