// Configuration store of Slic3r.

// The configuration store is either static or dynamic.
// DynamicPrintConfig is used mainly at the user interface. while the StaticPrintConfig is used
// during the slicing and the g-code generation.
//
// The classes derived from StaticPrintConfig form a following hierarchy.
//
// FullPrintConfig
//    PrintObjectConfig
//    PrintRegionConfig
//    PrintConfig
//        GCodeConfig

// ModelConfig is a wrapper around DynamicPrintConfig with an addition of a timestamp.
// Each change of ModelConfig is tracked by assigning a new timestamp from a global counter.
// The counter is used for faster synchronization of the background slicing thread
// with the front end by skipping synchronization of equal config dictionaries. 
// The global counter is also used for avoiding unnecessary serialization of config 
// dictionaries when taking an Undo snapshot.
//
// The global counter is NOT thread safe, therefore it is recommended to use ModelConfig from
// the main thread only.
// 
// As there is a global counter and it is being increased with each change to any ModelConfig,
// if two ModelConfig dictionaries differ, they should differ with their timestamp as well.
// Therefore copying the ModelConfig including its timestamp is safe as there is no harm
// in having multiple ModelConfig with equal timestamps as long as their dictionaries are equal.
//
// The timestamp is used by the Undo/Redo stack. As zero timestamp means invalid timestamp
// to the Undo/Redo stack (zero timestamp means the Undo/Redo stack needs to serialize and
// compare serialized data for differences), zero timestamp shall never be used.
// Timestamp==1 shall only be used for empty dictionaries.
