commit 08516d97a1b34cbb119d6d842ae31e4cb4e08740

    [cairo-directfb] Merging from directfb.org
    
    - Improved performance in case of surface conversion: allocate a shadow buffer that can only grow
    - Fixed support for small surfaces (less than 8x8)
    - Optimize the blending function according to the surface format
    - Added _directfb_categorize_operation(): selects the blitting function according to the transform matrix
    - Avoid inverting the matrix when doing a simple StretchBlit()
    - Use TextureTriangles() instead of StretchBlit() when scale factors are negative
    - Added support for ARGB32 fonts (converted to A8 internally)
    - Removed unused functions (flush() and mark_dirty_rectangle())
    - Code cosmetics
