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). |
