39aa5c27b5 A comparison of gl/cogl-texture.c and gles/cogl-texture.c, to reduce
differences and improve maintainability.

	* clutter/cogl/gl/cogl-context.h:
	Adds a CoglTextureGLVertex typedef + texture_vertices and
	texture_vertices_size members to CoglContext for using vertex arrays
	like GLES does

	* clutter/cogl/gl/cogl-context.c:
	Initializes texture_vertices + texture_vertices_size members

	* clutter/cogl/gl/cogl-internal.h:
	Adds COGL_ENABLE_COLOR_ARRAY

	* clutter/cogl/gl/cogl.c:
	Add COGL_ENABLE_COLOR_ARRAY support to cogl_enable

	* clutter/cogl/gles/cogl-context.h:
	Change the CoglTextureGLVertex to use GLfloat for the position
	and texture coord attributes and GLubyte for the color.

	* clutter/cogl/gles/cogl-texture-private.h:
	Adds a wrap_mode member like GL has.

	* clutter/cogl/gl/cogl-texture.c
	* clutter/cogl/gles/cogl-texture.c:
	Improves the comparability of the files, such that the remaining
	differences, better reflect the fundamental differences needed
	between GL and GLES. Notably GL no longer uses glBegin/glEnd for
	submitting vertices, it uses vertex arrays like GLES and this gives
	a small but measurable fps improvement for test-text.

* clutter/cogl/cogl-color.h:
	* 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:
	* clutter/cogl/cogl-deprecated.h: Added cogl-deprecated.h,
	an header file containing the deprecation symbols similar
	to clutter-deprecated.h.

	* clutter/clutter-entry.c:
	* clutter/clutter-label.c:

	is possible, and use cogl_set_source_color4ub() instead.

	* clutter/pango/cogl-pango-render.c: Ditto as above.

	* doc/reference/clutter/subclassing-ClutterActor.xml:
	* doc/reference/cogl/cogl-sections.txt: Update the documentation.

0ff710d37b Bug 1057 - cogl_texture_rectangle doesn't support backward
coordinates

	* clutter/cogl/gl/cogl-texture.c: Instead of sorting the vertex
	and texture coordinates passed to cogl_texture_rectangle, just
	swap both sets whenever the texture coordinates are backward.

	* clutter/cogl/common/Makefile.am:
	* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled

	* clutter/cogl/gles/cogl-texture.c (cogl_texture_polygon)
	(_cogl_texture_quad_sw, _cogl_texture_quad_hw): Enable backface

e43b7ddd3d Bug 1196 - Texture border drawing problems
* 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.

71133b3d0e * clutter/cogl/gles/cogl-gles2-wrapper.h (CoglGles2Wrapper): Added
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.

29f7cbdfb7 * clutter/cogl/gles/cogl-texture.c: Use the wrapper for
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

70dbc03734 GLES 2 backend
* 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.

f9e43c440b * clutter/cogl/gl/cogl.c (error_string):
* 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.

9f5a8edc64 * clutter/cogl/gles/cogl-texture.c:
(_cogl_texture_download_from_gl:) Only comment out the broken
	check for framebuffer alpha bits, not the check for alpha in
	texture format.
2008-05-21 10:00:08 +00:00
Ivan Leben
2008a03a6b * clutter/cogl/gles/cogl-texture.c:
(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.
2008-05-20 10:37:36 +00:00
Ivan Leben
3d9f83019d * clutter/cogl/gles/cogl-texture.c:
(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.
2008-05-19 15:21:56 +00:00
Ivan Leben
f2d701c809 * clutter/cogl/gl(es)/cogl.c: New internal function
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).

Ivan Leben
ef084cfa95 * clutter/cogl/cogl.h.in:
* 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-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.

	* clutter/cogl/gles/cogl-texture.c: 
	* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE

	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,
