Cogl 1.9.6                                                         2012-02-21

  • List of changes since Cogl 1.9.4

  » New conformance tests or tests ported from Clutter:
        test-offscreen
        test-primitive
        test-texture-3d
  » New public experimental functions:
        cogl_pipeline_get_layer_texture
        cogl_primitive_copy
        cogl_primitive_foreach_attribute
        cogl_primitive_get_indices
        cogl_pipeline_get_layer_{min,max}_filter
  » Added cogl_kms_renderer_get_kms_fd to get the KMS file descriptor.
  » Bug fixed in the KMS support where it would crash on cleanup if it
    couldn't save the CRTC state.
  » Bug fixed in the Wayland compositor support where it would leak
    EGLImages when creating a texture from a buffer
  » The swap_buffer callback in GLX is now delayed until
    cogl_poll_dispatch is called so that apps can handle it more
    predictably.
  » Fixes for bugs with pipelines that are trying to use a layer with
    a NULL texture.
  » New cogl_framebuffer_* API for drawing directly to the framebuffer
    without having to push the framebuffer. Ideally we want to move
    towards this style of API in future with no global stacks.
  » Most of the _EXP suffixes have been removed from the experimental
    API symbols in the hope that the gtk-doc unstable annotation will
    be enough to distinguish these.
  » Add a COGL_DEBUG=winsys option
  » CoglBuffer and CoglPrimitive now take an explicit CoglContext
    argument in their constructor. We want to move towards getting rid
    of the global context.
  » Updates to the MSVC build support.
  » Add cogl_pipeline_set_layer_null_texture(). This can be used for
    base pipelines instead of having to create a dummy texture.
  » Fix some bugs where Cogl was assuming there is a direct mapping
    between the pipeline layer number and the GL texture unit number.
  » In snippets, there are now always builtin sampler uniforms for
    every layer of the pipeline. This makes it easier to write GLSL
    that samples arbitrary units.
  » The texture lookup snippet hook now gets passed the sampler for
    the unit. The snippet can use this to sample the texture multiple
    times.
  » Some public constants for CoglPixelFormat have been removed
    (COGL_UNPREMULT_MASK, COGL_UNORDERED_MASK and
    COGL_PIXEL_FORMAT_{24,32}).
  » 30-bit pixel formats added.
  » COGL_DEBUG=wireframes now correctly renders primitives using
    vertex shader snippets.
  » cogl_framebuffer_swap_buffers and friends have been renamed to
    cogl_onscreen_swap_buffers.
  » If the experimental 2.0 API is requested, as far as possible the
    headers for the 1.0 API are no longer included. Define
    COGL_ENABLE_EXPERIMENTAL_API instead if you want to mix both APIs.

    https://bugzilla.gnome.org:

    #660188 - Color corruption with software rendering at 30-bit color depth
    #668385 - Missing G_END_DECLS in cogl-poll.h
    #668856 - Do not look for GLES2-only GLSL prototypes on GL
    #668913 - The journal for an offscreen doesn't get flushed when
              cogl_texture_get_data is called
    #669368 - Reading back texture fails with ‘Invalid operation’ + wrong image
    #669785 - Build fixes for COGL master (1.9.x)

  • Note the following conformance tests are currently failing with
    the GLES2 driver but they were also failing in 1.9.4:
    test_cogl_depth_test, test_cogl_sub_texture, test_cogl_texture_3d
