-\section interesting Summary of interesting classes
-
- - Data models: Model and subclasses, e.g. WaveFileModel
-
- - Graphical layers: Layer and subclasses, displayed on View and its
- subclass widgets.
-
- - Main window class, document class, and file parser: MainWindow,
- Document, SVFileReader
-
- - Turning one model (e.g. audio) into another (e.g. more audio, or a
- curve extracted from it): Transform, encapsulating the data that need
- to be stored to be able to reproduce a given transformation;
- TransformFactory, for discovering the available types of transform;
- ModelTransformerFactory, ModelTransformer and subclasses, providing
- the mechanisms for applying transforms to data models
-
- - Creating the plugins used by transforms: RealTimePluginFactory,
- FeatureExtractionPluginFactory.  See also the API documentation for
- Vamp feature extraction plugins at
- http://www.vamp-plugins.org/code-doc/.
-
- - File reading and writing code: AudioFileReader and subclasses,
- WavFileWriter, DataFileReader, SVFileReader
-
- - FFT calculation and cacheing: FFTModel, FFTDataServer
-
- - Widgets that show groups of editable properties: PropertyBox for
- layer properties (contained in a PropertyStack), PluginParameterBox
- for plugins (contained in a PluginParameterDialog)
-
- - Audio playback: AudioCallbackPlaySource and subclasses,
- AudioCallbackPlayTarget and subclasses, AudioGenerator
-
-\section model Data sources: the Model hierarchy
-
-   A Model is something containing, or knowing how to obtain, data.
-
-   For example, WaveFileModel is a model that knows how to get data
-   from an audio file; SparseTimeValueModel is a model containing
-   editable "curve" data.
-
-   Models typically subclass one of a number of abstract subclasses of
-   Model.  For example, WaveFileModel subclasses DenseTimeValueModel,
-   which describes an interface for models that have a value at each
-   time point for a given sampling resolution.  (Note that
-   WaveFileModel does not actually read the files itself: it uses
-   AudioFileReader classes for that.  It just makes data from the
-   files available in a Model.)  SparseTimeValueModel uses the
-   SparseModel template class, which provides most of the
-   implementation for models that contain a series of points of some
-   sort -- also used by NoteModel, TextModel, and
-   SparseOneDimensionalModel.
-
-   Everything that goes on the screen originates from a model, via a
-   layer (see below).  The models are contained in a Document object.
-   There is no containment hierarchy or ordering of models in the
-   document.  One model is the main model, which defines the sample
-   rate for playback.
-
-   A model may also be marked as a "derived" model, which means it was
-   generated from another model using some transform (feature
-   extraction or effect plugin, etc) -- the idea being that they can
-   be re-generated using the same transform if a new source model is
-   loaded.
-
-\section layer Things that can display data: the Layer hierarchy
-
-   A Layer is something that knows how to draw parts of a model onto a
-   timeline.
-
-   For example, WaveformLayer is a layer which draws waveforms, based
-   on WaveFileModel; TimeValueLayer draws curves, based on
-   SparseTimeValueModel; SpectrogramLayer draws spectrograms, based on
-   WaveFileModel (via FFTModel).
-
-   The most basic functions of a layer are: to draw itself onto a
-   Pane, against a timeline on the x axis; and to permit user
-   interaction.  If you were thinking of adding the capability to
-   display a new sort of something, then you would want to add a new
-   layer type.  (You may also need a new model type, depending on
-   whether any existing model can capture the data you need.)
-   Depending on the sort of data in question, there are various
-   existing layers that might be appropriate to start from -- for
-   example, a layer that displays images that the user has imported
-   and associated with particular times might have something in common
-   with the existing TextLayer which displays pieces of text that are
-   associated with particular times.
-
-   Although layers are visual objects, they are contained in the
-   Document in Sonic Visualiser rather than being managed together
-   with display widgets.  The Sonic Visualiser file format has
-   separate data and layout sections, and the layers are defined in
-   the data section and then referred to in the layout section which
-   determines which layers may go on which panes (see Pane below).
-
-   Once a layer class is defined, some basic data about it needs to be
-   set up in the LayerFactory class, and then it will appear in the
-   menus and so on on the main window.
-
-\section view Widgets that are used to show layers: The View hierarchy
-
-   A View is a widget that displays a stack of layers.  The most
-   important subclass is Pane, the widget that is used to show most of
-   the data in the main window of Sonic Visualiser.
-
-   All a pane really does is contain a set of layers and get them to
-   render themselves (one on top of the other, with the topmost layer
-   being the one that is currently interacted with), cache the
-   results, negotiate user interaction with them, and so on.  This is
-   generally fiddly, if not especially interesting.  Panes are
-   strictly layout objects and are not stored in the Document class;
-   instead the MainWindow contains a PaneStack widget (the widget that
-   takes up most of Sonic Visualiser's main window) which contains a
-   set of panes stacked vertically.
-
-   Another View subclass is Overview, which is the widget that
-   contains that green waveform showing the entire file at the bottom
-   of the window.

+\section interesting Summary of interesting classes
+
+ - Data models: Model and subclasses, e.g. WaveFileModel
+
+ - Graphical layers: Layer and subclasses, displayed on View and its
+ subclass widgets.
+
+ - Main window class, document class, and file parser: MainWindow,
+ Document, SVFileReader
+
+ - Turning one model (e.g. audio) into another (e.g. more audio, or a
+ curve extracted from it): Transform, encapsulating the data that need
+ to be stored to be able to reproduce a given transformation;
+ TransformFactory, for discovering the available types of transform;
+ ModelTransformerFactory, ModelTransformer and subclasses, providing
+ the mechanisms for applying transforms to data models
+
+ - Creating the plugins used by transforms: RealTimePluginFactory,
+ FeatureExtractionPluginFactory.  See also the API documentation for
+ Vamp feature extraction plugins at
+ http://www.vamp-plugins.org/code-doc/.
+
+ - File reading and writing code: AudioFileReader and subclasses,
+ WavFileWriter, DataFileReader, SVFileReader
+
+ - FFT calculation and cacheing: FFTModel, FFTDataServer
+
+ - Widgets that show groups of editable properties: PropertyBox for
+ layer properties (contained in a PropertyStack), PluginParameterBox
+ for plugins (contained in a PluginParameterDialog)
+
+ - Audio playback: AudioCallbackPlaySource and subclasses,
+ AudioCallbackPlayTarget and subclasses, AudioGenerator
+
+\section model Data sources: the Model hierarchy
+
+   A Model is something containing, or knowing how to obtain, data.
+
+   For example, WaveFileModel is a model that knows how to get data
+   from an audio file; SparseTimeValueModel is a model containing
+   editable "curve" data.
+
+   Models typically subclass one of a number of abstract subclasses of
+   Model.  For example, WaveFileModel subclasses DenseTimeValueModel,
+   which describes an interface for models that have a value at each
+   time point for a given sampling resolution.  (Note that
+   WaveFileModel does not actually read the files itself: it uses
+   AudioFileReader classes for that.  It just makes data from the
+   files available in a Model.)  SparseTimeValueModel uses the
+   SparseModel template class, which provides most of the
+   implementation for models that contain a series of points of some
+   sort -- also used by NoteModel, TextModel, and
+   SparseOneDimensionalModel.
+
+   Everything that goes on the screen originates from a model, via a
+   layer (see below).  The models are contained in a Document object.
+   There is no containment hierarchy or ordering of models in the
+   document.  One model is the main model, which defines the sample
+   rate for playback.
+
+   A model may also be marked as a "derived" model, which means it was
+   generated from another model using some transform (feature
+   extraction or effect plugin, etc) -- the idea being that they can
+   be re-generated using the same transform if a new source model is
+   loaded.
+
+\section layer Things that can display data: the Layer hierarchy
+
+   A Layer is something that knows how to draw parts of a model onto a
+   timeline.
+
+   For example, WaveformLayer is a layer which draws waveforms, based
+   on WaveFileModel; TimeValueLayer draws curves, based on
+   SparseTimeValueModel; SpectrogramLayer draws spectrograms, based on
+   WaveFileModel (via FFTModel).
+
+   The most basic functions of a layer are: to draw itself onto a
+   Pane, against a timeline on the x axis; and to permit user
+   interaction.  If you were thinking of adding the capability to
+   display a new sort of something, then you would want to add a new
+   layer type.  (You may also need a new model type, depending on
+   whether any existing model can capture the data you need.)
+   Depending on the sort of data in question, there are various
+   existing layers that might be appropriate to start from -- for
+   example, a layer that displays images that the user has imported
+   and associated with particular times might have something in common
+   with the existing TextLayer which displays pieces of text that are
+   associated with particular times.
+
+   Although layers are visual objects, they are contained in the
+   Document in Sonic Visualiser rather than being managed together
+   with display widgets.  The Sonic Visualiser file format has
+   separate data and layout sections, and the layers are defined in
+   the data section and then referred to in the layout section which
+   determines which layers may go on which panes (see Pane below).
+
+   Once a layer class is defined, some basic data about it needs to be
+   set up in the LayerFactory class, and then it will appear in the
+   menus and so on on the main window.
+
+\section view Widgets that are used to show layers: The View hierarchy
+
+   A View is a widget that displays a stack of layers.  The most
+   important subclass is Pane, the widget that is used to show most of
+   the data in the main window of Sonic Visualiser.
+
+   All a pane really does is contain a set of layers and get them to
+   render themselves (one on top of the other, with the topmost layer
+   being the one that is currently interacted with), cache the
+   results, negotiate user interaction with them, and so on.  This is
+   generally fiddly, if not especially interesting.  Panes are
+   strictly layout objects and are not stored in the Document class;
+   instead the MainWindow contains a PaneStack widget (the widget that
+   takes up most of Sonic Visualiser's main window) which contains a
+   set of panes stacked vertically.
+
+   Another View subclass is Overview, which is the widget that
+   contains that green waveform showing the entire file at the bottom
+   of the window.
