Sonic visualiser

Support 64-bit builds on OS/X (using CoreAudio instead of obsolete QuickTime audio file reader)

Simplify RDF reading and fix some bugs. Now requires Dataquay

(http://breakfastquay.com/dataquay/) rather than using Redland
directly. Release builds use Sord/Serd rather than Redland

Add a fullscreen mode on the F11 key

Add session templates; save session as template; apply template to session

Tidy up the file open logic so as to remove the dialog asking how to open a file, where possible

Various bug fixes.

Sonic Visualiser now registers as a file type handler on OS/X,

providing better integration with the desktop generally (Dan Stowell)

- There is a new function to toggle all Time Rulers at once (key #)

- The CSV import dialog has been overhauled, allowing more flexible
selection of purpose for each column

- Text overlays are now easier to read on dark backgrounds

- Hidden layers are now ignored when exporting an image (Dan Stowell)

- A crash when starting a new session or exiting the application
after loading a session with saved alignment data has been fixed

- The duplication of right-button menu functions when multiple files
were loaded has been fixed

- The layer-add menu functions now have shortcuts (Dan Stowell)

- The codebase has been reorganised into libraries and a configure
step added. It should be easier to build and maintain on OS/X and
Linux than previously, although it won't make much difference on
Windows.

- A Czech translation is now included (thanks to Pavel Fric).

The RDF importer does a better job of assigning labels to layers,

layers to panes, and values to labelled regions

- Interactive editing in the Text layer benefits from the same
improvements as made in 1.7 to Note and Region layers

- The layer data editor window has a text search feature

- The main window status bar now shows the last label to have passed
the playback position in the current layer, at the right end of the
status bar

- The Russian translation has been updated (thanks Alexandre)

A new "Insert Item At Selection" function on the Edit menu

can be used to create Note and Region layer items whose time
extents correspond to the current selection(s)

- Interactively editing points in the Note and Region layers
now works much more smoothly

- SV can now import MIDI files that use SMPTE timecode for event
timing (importing MIDI files using with the more common
timebase-based timing was already supported)

- Time values throughout the display may optionally be shown in
seconds and frames at various frame rates

- A crash on exit in Windows has been fixed

- A very unobtrusive user survey is now included

- Various other bug fixes.

The Colour 3D Plot layer now supports logarithmic vertical

scale and linear interpolation options.

- A new colour scheme (High Gain) has been added for spectrogram
and Colour 3D Plot, which improves readability for some data.

- Further performance improvements have been made to Colour 3D
Plot.

- Various other bug fixes.

Changes in Sonic Visualiser 1.5 since the previous version 1.4:

- You can now insert time instants, time values, and notes using
a MIDI device during playback. If a time value or note layer is
current it will be used for insertion (giving a value equal to
the pitch class, or the played note, respectively); otherwise an
existing or new time instants layer will be used just as it is
when inserting instants using the PC keyboard. Using a MIDI
device should give better timing than using the PC keyboard.

- There is a new Activity Log window with a (purely informative) list
of events and user interactions that happen while SV is running.

- The spectrogram has somewhat improved graphical scaling, and
this is now the default (being much faster than the 4x oversampled
method). The previous default is still available as a preference.

- Visualisation of very dense colour plots (such as spectrograms
calculated by plugins) is substantially faster in this release.

- Spectrogram display is now faster in many circumstances.

- Alignment using the MATCH plugin is faster on OS/X than before.

- SV will take into account RDF plugin descriptions, if available,
in order to make somewhat better decisions about display of plugin
outputs (for example, placing segmentation data into a layer with
segmentation plot type).

- You can now switch layers by clicking on the spare area at the left
end of the pane that is also used for the current pane indicator.

- The vertical black lines dividing segments in the time value
layer's segmentation plot style are now optional.

- Several widget layout bugs on OS/X have been fixed.

- Several serious crashing, deadlock, and data corruption bugs have
been fixed.
