    ImpGraphic: rename Impl{Read,Write}Embedded - used only in swapping
    
    ImplReadEmbedded and ImplWriteEmbedded are used when swapping only
    so rename it to swapInContent and swapOutContent.
    
    In addition change the swapInFromStream to accept SvStream by
    reference and not pointer.

    basegfx::MirrorDirectionFlags as replacement for BmpMirrorFlags
    
    BmpMirrorFlags in Bitmap is an attribute for bitmap manipulation
    (mirroring). This change creates a copy of the flags in basegfx
    as MirrorDirectionFlags, which will be used in the fututre as a
    general repalcement for the BmpMirrorFlags, that will be changed
    step by step.
    
    For now we only use the flags in GraphicAttr to make it independent
    form vcl, and cast to/from BmpMirrorFLags and MirrorDirectionFlags
    where needed.

    Separate core drawinglayer func. into drawinglayercore library
    
    This separates the drawinglayer core functionallity into a
    separate library, to keep a strict separation what is backend
    dependent and what is not. More strict separation can be done
    at a later date.
    
    This will make it possible to push part of drawinglayer
    (part of processor2d) directly into VCL.

    tdf#135432 native-code: Add missing include for locales
    
    While commit ed8bce1909f658d8e3d950f374931242f91ba811
    ("fix i18n constructors and android scripts", 2020-08-12)
    had added the missing constructors to the native-code.py
    script after commit 155c056b1d4674d5ff73bbb5e1ad1dcd1e6aae36
    ("i18npool: create instances with uno constructors",
    2020-07-29), the include for the header containing the
    corresponding 'WITH_LOCALE_*' defines was missing,
    so expressions like
    
        #if WITH_LOCALE_ALL || WITH_LOCALE_ja
    
    always evaluated to 0, effectively always keeping the
    constructors from actually being included.
    
    Therefore, add the missing 'config_locales.h' include.
