* SpinInput : Code refactoring
* BitmapToggleButton :
* Create wxBitmapToggleButton if control doesn't have a label and wxToggleButton otherwise
* Linux specific: Calculate default size from label size
+ Tab: Linux specific: Set background color for tree_ctrl and don't set background color for Tab
* Fixed new font applying for TreeCtrl and DataViewCtrl
* Fixed update of the em_unit in respect to the new font size
+ MSW specific: Fixed re-scaling of the non-standard buttons
* Non-MSW specific: Next improvements for BG of the controls
+ Create wrap class BitmapToggleButton to correct create under all platforms
+ TabFilament: Fixes crash on recreating of the app
* Next improvements for background under nonMSW systems
+ Fixed Field::SpinCtrl::propagate_value
* DropDown: Implemented transparent background for rounded corners.
+ Tab: use TextInput and SwitchButton for substitutions
+ nonMSW specific: Don't set BackgroundColors for panels
* ObjectManipulation: Use TextInput instead wxTextCtrl
* Process rectangle/rounded controls
+ Preferences: Added "Suppress round corners" parameter
* Skinned UI: SwitchButton. Use it for CheckBox Field
* Skinned UI: SpinInput
+ ScalableBitmap/ScalableButton respects to different width and height of bitmap.
* Skinned UI: ComboBox
* Skinned UI: CheckBox
(Added missed cleaning of the m_chb_match_single_lines on Delete All substitutions)
+ Added missed Layout on add substitution
+ EditGCodeDialog: Deleted unused code caused compilation warning.
+ Fixed visibility of the "Match single line" CheckBoxes, when preset is switched and values are transferred to new selected preset.
+ Fixed typos in some functions names
* Check errors state on all places of its using (throw exceptions or show a warnings message)
+ To backward compatibility, save "thumbnails_format" value to the config
+ deep_diff() function is extended for the case of "thumbnails" comparison
+ Added unit tests to:
* check a load of configuration for "thumbnails" and "thumbnails_format" options
* check return values for make_and_check_thumbnail_list() function

wxEXPAND overrides alignment flags in box sizers
WIP GCode/SmoothPath.cpp,hpp cache for interpolating extrusion path with arches.
Removed Perl test t/geometry.t, replaced with C++ tests.
Refactored ExtrusionEntity and derived classes to hold extrusion attributes in new ExtrusionFlow/ExtrusionAttributes classes.
Reworked path ordering in G-code export to never copy polylines, but to work with a new "flipped" attribute.
Reworked G-code export to interpolate extrusion paths with smooth paths and to extrude those smooth paths.
New parameters: arc_fitting, arc_fitting_tolerance
Renamed GCode class to GCodeGenerator
Moved GCodeWriter.cpp/hpp to GCode/
Moved Wipe from from GCode.cpp,hpp to GCode/Wipe.cpp,hpp
Moved WipeTowerIntegration from GCode.cpp,hpp to GCode/WipeTowerIntegration.cpp,hpp
New variant of douglas_peucker() to simplify range of iterators in place.
Refactored wipe in general and wipe on perimeters / hiding seams.
WIP: Convert estimate_speed_from_extrusion_quality() and its application to smooth paths.
WIP: Cooling buffer to process G2G3, disable arc fitting for filters that cannot process it.
