Extended ConfigBase with set() functions similar to the upstream Slic3r.
ConfigBase::set_deserialize() newly throws if the operation fails.
Extrusion width parameters are newly tested for negative values.
Reworked the FFF testing framework & ConfigBase::set_deserialize()
for more compact tests: set_deserialize() now accepts list
of key / value pairs.
Fixed an incorrect assert in LayerRegion.
DynamicPrintConfig::full_print_config()
new cheaper constructors of DynamicConfig / DynamicPrintConfig from ConfigBase
Unit tests: ported test_model from upstream Slic3r, thanks @lordofhyphens
Unit tests refactored to use less autos and initializer lists for readibility,
DynamicPrintConfig is handled by value, not by shared pointer.
Integration of the "cereal" serialization library.
Serialization / deserialization of the DynamicConfig / DynamicPrintConfig.
DynamicPrintConfig serializes ordinal identifiers instead
of the option key strings to conserve space.
Reworked command line processing for the GUI slic3r. Now the config is loaded first, then the model files (also the configs from AMF/3MF are applied), and lastly the free standing parameters are applied.
Fixed unescaping for command line parameters. The string parameters are now not unescaped, string vector parameters are unescaped only if enquoted.
Tab::load_current_preset() - disabled CallAfter for predictability. With CallAfter, it was difficult to call the method in sequence with other methods.
Fixed some missing ->Destroy() calls on dialogs created from MainFrame
Fixed some compiler warnings.
Added synchronization of GCodePreviewData between the front end / back end
(GCodePreview data is only used if PrintStep psGCodeExport is finished).
Added reset of GCodePreviewData on Print::apply() to conserve RAM.
