[Enrico Weigelt, metux IT consult]

Hi folks,


here's the 4th take of my DRM fixes for review.

Added some more core patches and cleanups in the DRM backend patches.

    cairo_bool_t
  drm: use typedefs and defines from drm.h instead of redundant own

    type
  drm: fixed missing includes
  drm: fixed cairo_status_t vs cairo_int_status_t mixup

  drm: fixed calls to _cairo_botor_scan_converter_add_polygon()
  drm: fixed handling of private pointers in scaled_font objects
  drm: fixed test for whether path is a box
  drm: add helper for typecasting from abstract device to drm device
    type
  drm: fixed return value of _device_flush()

  drm: fixed call to _cairo_atomic_ptr_cmpxchg()
  drm: cleaned up device probing / initialization
  drm: fixed surface backend ops vectors
  drm: fixed calls to surface backend flush() operations

  drm: fixed calls to _cairo_surface_init()
  drm/intel: consolidated INTEL_GLYPH_CACHE_* with GLYPH_CACHE_*
  drm/intel: renamed intel_glyph_cache_add_glyph()::glyph to
    glyph_private
  drm/intel: intel_scaled_glyph_fini(): renamed local priv variable for
    better consistency
  drm/intel: fixed prototyp of intel_scaled_glyph_fini()
  drm/intel: store scaled_glyph pointer in intel_glyph structure
  drm/intel: make struct _intel_glyph container of
    cairo_scaled_glyph_private_t
  drm/intel: destructor for glyph cache node
  drm/intel: fix font cleanup
  drm/i915: fixed calls to _cairo_clip_get_region()
  drm/i915: fixup call to _cairo_boxes_extents()
  drm/i915: split image_caches array into struct for better readability
  drm: fixed _cairo_clip_*() calls
  drm: replace use of _cairo_clip_to_boxes()
  drm/i915: fixed call to _cairo_pattern_sampled_area()
  qt: replaced calls to _cairo_clip_init_copy() by _cairo_clip_copy()
  core: changed retval of _cairo_composite_rectangles_init_for_mask() to
    cairo_bool_t
  core: changed retval of _cairo_composite_rectangles_init_for_paint()
    to cairo_bool_t
