 * Floating point DNG support:
    - new data fields:
      imgdata.rawdata.float_image - bayer float data
      imgdata.rawdata.float3_image - 3-component float data
      imgdata.rawdata.float4_image - 4-component float data
      imgdata.color.fmaximum - float data maximum (calculated from real data,
          rounded to 1.0 if below 1.0)
   - new raw processing flag
      LIBRAW_PROCESSING_CONVERTFLOAT_TO_INT - converts float data to 16-bit
        integer immediately after decoding with default parameters
   - new API Calls:
      int LibRaw::is_floating_point() returns non-zero if RAW file contains
          floating point data
      int LibRaw::have_fpdata() returns non-zero if rawdata.float*_image is not
        null
      LibRaw::convertFloatToInt(float dmin=4096.f, float dmax=32767.f,
           float dtarget = 16383.f)
        converts float/float3/float4_image to raw_image/color3/color4_image
        with or without scaling:

 * New API calls
    unsigned LibRaw::capabilities and C-API libraw_capabilities()
    allows developers to determine LibRaw compile flags at runtime.
    Returns ORed bit fields:
    LIBRAW_CAPS_RAWSPEED - LibRaw was compiled with RawSpeed Support
    LIBRAW_CAPS_DNGSDK - LibRaw was compiled with Adobe DNG SDK
    LIBRAW_CAPS_DEMOSAICSGPL2, LIBRAW_CAPS_DEMOSAICSGPL3 - LibRaw was compiled with
      demosaic packs (GPL2/GPL3)

 * More metadata parsed:
    - White balance coefficients stored in the raw file are extracted into:
     int imgdata.color.WBCoeffs[256][4] - array indexed by EXIF lightsource type
        for example, WBCoeffs[21][..] contains coefficients for D65 lightsource
     float imgdata.color.WBCT_Coeffs[64][5] contains white balance data specified
       for given color temperature: WBCT_Coeffs[i][0] contains temperature value,
       and [1]..[4] are WB coefficients.
    - DNG analog balance, per-channel black/white level, and forward matrix
    - vendor specific metadata stored in vendor-specific data structures

 * new C-API calls:
    void libraw_set_user_mul(libraw_data_t *lr,int index, float val);
    void libraw_set_ca_correction(libraw_data_t *lr,int ca_correc,
           float ca_red, float ca_blue);
    void libraw_set_cfalinenoise(libraw_data_t *lr,int cfaline, float linenoise);
    void libraw_set_wf_debanding(libraw_data_t *lr, int wf_debanding,
           float wfd0, float wfd1, float wfd2, float wfd3);
    void libraw_set_interpolation_passes(libraw_data_t *lr,int passes);
