    glamor_dump_pixmap: Add helper routine to dump pixmap.
    
    For debug purpose only to dump the pixmap's content.
    As this function will call glamor_prepare_access/glamor_finish_access
    internally. Please use it carefully.

    glamor_fill/tile: Fixed a tileX/tileY calculation bug.
    
    The previous's calculation is incorrect, now fix it and then
    we don't need to fallback at glamor_tile.

    prepare_access: Don't use fbo after it was downloaded.
    
    We add a new gl_fbo status GLAMOR_FBO_DOWNLOADED to indicate
    the fbo was already downloaded to CPU. Then latter the access
    to this pixmap will be treated as pure CPU access. In glamor,
    if we fallback to DDX/fbXXX, then we fallback everything
    currently. We don't support to jump into glamor acceleration
    layer between a prepare_access/finish_access. Actually, fbCopyPlane
    is such a function which may call to acceleration function within
    it. Then we must mark the downloaded pixmap to another state
    rather than a normal fbo textured pixmap, and then stick to use
    it as a in-memory pixmap.

    glamor_eglmodule: Change module name according to normalize naming rule.
    
    As Xorg module loader will normalize module name which will
    remove '_' when we put "glamor_egl" to the configure file,
    then it will fail to find us.

    Don't call dixSetPrivate directly.
    
    We may change the way to set/get those private data latter.
    consolidate to glamor_set_pixmap/screen_private is better
    than call those dixSetPrivate directly.

    Refine CloseScreen and FreeScreen processes.
    
    This commit move the calling to glamor_close_screen from
    glamor_egl_free_screen to glamor_egl_close_screen, as this
    is the right place to do this.
    
    We should detach screen fbo and destroy the corresponding
    KHR image at glamor_egl_close_screen stage. As latter
    DDX driver will call DestroyPixmap to destroy screen pixmap,
    if the fbo and image are still there but glamor screen private
    data pointer has been freed, then it causes segfault.
    
    This commit also introduces a new flag GLAMOR_USE_EGL_SCREEN.
    if DDX driver is using EGL layer then should set this bit
    when call to glamor_init and then both glamor_close_screen
    and glamor_egl_close_screen will be registered correctly,
    DDX layer will not need to call these two functions manually.
    This way is also the preferred method within Xorg domain.
    
    As interfaces changed, bump the version to 0.3.0.
