Cogl 1.9.8                                                         2012-03-05

  • List of changes since Cogl 1.9.6

  » Various Visual Studio build fixes
  » Correctly check for GL_EXT_packed_depth_stencil and support using
    GL_OES_packed_depth_stencil on GLES2
  » Correctly handle pre-multiplied alpha conversions when reading
    back texture data.
  » Added cogl_renderer_{get,set}_driver functions so the underlying
    driver can be chosen programmatically.
  » Revamped the conformance testing framework so that it
    automatically runs every test against GLES2 as well as GL and also
    against all of the pipeline backends and with npot textures
    disabled.
  » Add a conformance test for reading back an RGBA texture as
    alpha-only
  » Added support for converting between all of Cogl's supported pixel
    formats including pre-multiplied alpha conversions.
  » Added conformance tests for converting to and from all of the
    supported formats.
  » Added a public cogl_framebuffer_read_pixels_into_bitmap()
    function which will effective read into a CoglPixelBuffer.
  » CoglPixelBuffer was changed to no longer have associated width,
    height and format information and instead we will rely on
    CoglBitmap to track that informations. The relationship is
    analogous how CoglAttributes relate to CoglAttributeBuffers
    and means for example that a CoglPixelBuffer could now be used
    to hold multiple images.
  » Added public cogl_bitmap_get_{width,height,format,rowstride} api
  » Added a public accessor for the underlying pixel buffer of a
    CoglBitmap.
  » Added various missing cast macros for some buffer objects.
  » Ported the Clutter based test-pixel-buffer test to be standalone.
