Gwyddion Files

Application:
- Pango 1.10 and Cairo 1.2 are now required.
- The program should start with a saner working directory by default.
- Translations updated: Czech, French, Russian.
- New translation: Korean.

Libraries:
- libgwyddion: A function for copying GwySIValueFormat was added; the
  structure is also registered as a boxed type now.
- libgwydgets: gwy_axis_get_magnification_string() returns string for the new
  units after gwy_axis_set_si_unit().
- libgwydraw: Adaptive false colour mapping was improved by making it more
  adaptive.
- libgwydraw: It is possible to map user-given values to gradient positions
  using the same mapping as gwy_pixbuf_draw_data_field_adaptive() uses.
- libgwydgets: GwyColorAxis has a new ‘unlabelled’ ticks mode in which the
  interior ticks are drawn without labels.
- libgwydgets: GwyColorAxis permits specifying a non-linear value to gradient
  mapping function.
- libgwydgets: Crash when changing color maps in Gwy3DView with gtk+ version
  greater 2.29 was fixed.
- libgwyapp: When adaptive false colour mapping is used, the axis is set to
  the new ‘unlabelled’ mode so the mapping non-linearity can be seen.

Modules:
- Image export (new): Replaces image rendering in the pixmap module; can
  export to vector graphics formats: PDF, EPS and SVG.  The corresponding
  file types are called ‘pdfcairo’, ‘pngcairo’, etc.
- NX II (new): Imports EMSYS NX II AFM files.
- FemtoScan (new): Imports FemtoScan SPM files.
- SPMx (new): Imports ACT/FemtoScan SPMxFormat files.
- Fractional Brownian motion (new): Generation of fBm-like artifical
  surfaces.
- Renishaw (new): Imports Renishaw WiRE data files.
- Pixmap: Only used for image import; image rendering functions were removed.
- Statistical quantities: Crash in saving the statistics was fixed (introduced
  in 2.38).
- OpenGPS: Format detection was improved to check not just for the presence
  of main.xml also if it really looks like an ISO 5436-2 XML file.
- MIF: X, Y and Z calibration factors are applied to data upon import and
  a different Z conversion formula is used according to z_linearized.
  Multiplicative factors encoded after the image are applied to the data.
- MetroPro: Z scale in files with PhaseRes value of 2 is correct now.
- Grain distributions: The graph abscissas are bin centres now, as is usual,
  instead of bin left edges.
- Noise and line noise synthesis: Settings are remembered also on Cancel.
