// CleanupSettingsModel declaration
//********************************************************************
//! The CleanupSettingsModel is the class responsible for concrete management of
//! cleanup settings in Toonz.
/*!
In Toonz, the interface to cleanup settings follows the model/view
architecture,
where each Cleanup Settings panel is a view to a singleton model of this
class.
\n\n
The CleanupSettingsModel is responsible for handling signals that involve
cleanup
changes, such as user changes in the parameters coming from views, settings
reset or
switches from commands, and so on.
\n\n
A cleanup operation is roughly split in 2 parts: main processing and
post-processing.
\n\n
The main processing part takes the full original image and applies geometric
transforms
and other full-image analysis and processing. This is typically slow, and is
thus
performed by this class once for all views.
\n\n
Post-processing performs further local or pixel-per-pixel adjustments that are
sufficiently
fast to be carried out by single views on their preview area. This includes
<I> colors recognition,
colors adjustment, despeckling <\I> and \a antialiasing-related effects.
\note This class also acts as a wrapper to CleanupParamaters' palette, attaching
to the
"current cleanup palette handle" accessible through the
TPaletteController.
