Summary of changes:

Libraries:
- libgwyprocess: GwySpectra has properties specifying the abscissa and
ordinate labels for the spectra curves.
- libgwyprocess: Pass a NULL error array to gwy_nlfit_preset_fit() works now.
- libgwyprocess: New fitting presets: Two-Gaussian PSDF and parabolic step.
- libgwydgets: In 3D View masked data points can be made completely
transparent.
- libgwyddion: Aborting/crashing on deserialisation of invalid-sized arrays
was fixed.

Modules:
- Flatten base (new): Flattens the base of a surface with positive features.
- K-medians (new): K-medians clustering for volume data.
- SEM image (new): Presentation resembling SEM image corresponding to given
topography.
- XYZ export (new): Exports channel values to simple XYZ text file.
- Image export: It is possible do disable the frame if there are no rulers.
False colour rendering for inverted gradients and default non-full mappings
was corrected. Title centering for non-square images was corrected. A mask
colour sample can be rendered below the image with a label. Error message
saying ‘Success’ when exporting BMP files was fixed.
- APE DAX: Can also import APDT files now.
- NetCDF: The new setpoint variable ‘sranger_mk2_hwi_mix0_set_point’ is used
for metadata, if found.
- NRRD: 3D data with all three resolutions large are loaded a volume data
instead of sequences of channels.
- Merge: Can mask pixels in the result that were outside of either image. It
is also possible to automatically crop the result to only inside pixels.
A new merge type ‘Interpolation’ produces smoother transitions than the old
‘Smooth’ which was renamed to ‘Average’.
- Spectro tool: Uses abscissa and ordinate labels from the spectra object, if
present.
- Omicron, Nanoeducator: X and Y spectra axis labels are set according to the
imported spectrum type.
- Euclidean distance transform: Function for mask thinning was added.
- Mark by threshold: Percentage interpretation for inverted height was
changed to be less confusing.
- Raw XYZ: The square image option is not enforced on regular grid data when
it is not available in the dialog.
- WITec Project: WIT_PR06 recognized as another variant of magic header.
- APE DAX, NanoObserver, NanoScanTech, OpenGPS, SPMx: Opening of files with
non-ASCII names should work better on MS Windows.

Other:
- Does not attempt to build the hdrimage module with C++ compiler unavailable.
