Bug 1209 - Move fixed point API in COGL
* clutter/cogl/cogl-fixed.h:
* 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.
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-primitives.c:
* clutter/cogl/common/cogl-primitives.h: Update internal usage of
ClutterFixed to CoglFixed.
* clutter/cogl/gl/Makefile.am:
* clutter/cogl/gl/cogl-primitives.c:
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gl/cogl.c: Ditto, in the GL implementation of the
COGL API.

* clutter/pango/pangoclutter-glyph-cache.h: Ditto, in the Pango
renderer glyphs cache.
* clutter/clutter-fixed.c:
* clutter/clutter-fixed.h: ClutterFixed and related API becomes
a simple transition API for bindings and public Clutter API.

* clutter/cogl/gl/cogl-texture.c (cogl_texture_polygon)
(_cogl_texture_quad_sw, _cogl_texture_quad_hw):
* clutter/cogl/gles/cogl-texture.c (cogl_texture_polygon)
(_cogl_texture_quad_sw, _cogl_texture_quad_hw): Enable backface
culling in GL if it is requested.
* clutter/cogl/gles/cogl-texture.c (_cogl_texture_quad_sw)
(_cogl_texture_quad_hw):
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
(_cogl_texture_quad_hw): Reorder the
vertices so that they are counter-clockwise.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Added a flag to
store whether backface culling is currently enabled.
* clutter/cogl/gles/cogl.c (cogl_enable_backface_culling):
* clutter/cogl/gl/cogl.c (cogl_enable_backface_culling): New
function
* doc/reference/cogl/cogl-sections.txt: Add
cogl_enable_backface_culling
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_upload_subregion_to_gl)
(_cogl_texture_upload_to_gl):
* clutter/cogl/gles/cogl-texture.c (_cogl_texture_upload_to_gl)
(_cogl_texture_upload_subregion_to_gl):
When uploading data to a sliced texture, fill the waste pixels
with copies of the edge of the real texture data. Otherwise the
value of the waste pixels are undefined so it will show artifacts
when the texture is scaled with GL_LINEAR and the pixels are
blended in.
* clutter/cogl/gl/cogl-texture.c (cogl_texture_set_region):
* clutter/cogl/gles/cogl-texture.c (cogl_texture_set_region):
Don't attempt to upload any data if the width or height of the
subregion is zero. Thanks to Gwenole Beauchesne.
uniforms for alpha testing.
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_gles2_wrapper_init): Get the uniforms for alpha testing
settings.
(cogl_wrap_glEnable, cogl_wrap_glDisable): Enable/disable alpha
testing.
(cogl_wrap_glAlphaFunc): Filled in the wrapper.
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: Added alpha
testing.
* clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_wrap_glGetIntegerv): Added a wrapper for glGetIntegerv so
that it can report zero clip planes.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gles/cogl-texture.c: Use the wrapped version of
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.
glTexParameteri. Call glGenerateMipmap after every change to the
texture image data.
* clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c: Added a wrapper for
glTexParameteri so that it can ignore requests to set
GL_GENERATE_MIPMAP. Added a wrapper for glGenerateMipmap that does
nothing on GLES 1
* 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
clutter-egl-headers.h so that the right version can be used
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
was being called before the GL context was bound so it didn't work
anyway and it was causing trouble for the GLES 2 simulator.
* clutter/cogl/gles/stringify.sh: Shell script to convert the
shaders into a C string.
* clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c: Wrappers for most of the
missing GL functions in GLES 2.
* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl:
* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: New shaders for
GLES 2
* clutter/cogl/gles/cogl-defines.h.in: Use the @CLUTTER_GL_HEADER@
macro instead of always using the GLES 1 header.
* clutter/cogl/gles/cogl-context.h (CoglContext): Include a field
for the state of the GLES 2 wrapper.
* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gles/cogl-primitives.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):
* clutter/cogl/gles/cogl-texture.c (cogl_texture_new_from_foreign):
GE(*) can't be used to wrap around calls that use the return
value.
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
(_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_texture_download_from_gl:) Implemented a workaround
for missing alpha framebuffer channel. There are still
some issues with detecting whether alpha is present in the
framebuffer. See comments in code. Test-cogl-tex-getset now
successfully retrieves a RGBA texture image data.
(cogl_texture_download_from_gl:) Store old blending factors
and restore them when done. The lack of ability to retrieve
the alpha channel now more noticable in test-cogl-tex-getset
since the edges of the hand are not antialiased.
* clutter/cogl/gl(es)/cogl-internal.h: Declare
cogl_blend_func to avoid "implicit implementation" compile
warning.
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).
* clutter/cogl/gl(es)/cogl-texture.h:
* clutter/cogl/gl(es)/cogl-texture.c:
cogl_texture_new_* functions take a gboolean auto_mipmap argument.
If TRUE automatic mipmap generation is enabled during the process
of slice texture object creation.
(cogl_texture_new_from_foreign:) now allows mipmap min filter
flags.
* clutter/clutter-texture.c:
* clutter/glx/clutter-glx-texture-pixmap.c:
* tests/test-cogl-offscreen.c:
* tests/test-cogl-tex-tile.c:
* tests/test-cogl-tex-convert.c:
* tests/test-cogl-tex-polygon.c:
* tests/test-cogl-tex-getset.c:
Pass FALSE for auto_mipmap to cogl_texture_new_*.
* clutter/pango/pangoclutter-render.c:
(tc_get:) Pass TRUE to cogl_texture_new_with_size and use mipmap
min filter for nicer glyphs at small scales. As a result test-text
has gone all beautiful now.
wrapped in reference-counted CoglHandles instead.
* clutter/cogl/gl/cogl-shader.c:
* clutter/cogl/gl/cogl-shader.h:
* clutter/cogl/gl/cogl-program.c:
* clutter/cogl/gl/cogl-program.h:
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.
* clutter/cogl/gles/cogl-defines.h.in:
* clutter/cogl/gl/cogl-defines.h.in: Removed COGLhandle
* clutter/cogl/gl/cogl-context.h: Added handle arrays for programs
and shaders.
* clutter/cogl/gl/cogl-context.c (cogl_create_context): Added
initialisers for shader_handles and program_handles.
(cogl_destroy_context): Added calls to g_array_free for all handle
arrays.
* clutter/cogl/gl/Makefile.am (libclutter_cogl_la_SOURCES): Added
cogl-{program,shader}.{c,h}
* clutter/cogl/common/Makefile.am
(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.
