(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.
