* Fixed a crash on preset changing and press Cancel button in SavePresetDialog
* Added Cancel button for MessageDialog after check "Remember my choice"
SplashScreen
* Set Version string in respect to the height of a Title string
* Added "Remember my choice" checkbox
* Center on the screen and set position in respect to the position of mainframe or settings dialog
Preferences : Added checkboxes for enable/suppress showing of the UnsavedChangeDialog
SearchImGui : close after parameter selection_is_changed_according_to_physical_printers
PhysicalPrinterDialog, SavePresetDialog : Center on the screen
on application start-up, at least not on Windows.
wxEVT_CREATE was called for some control deep in the Plater, however
the event was delivered to the main frame and only for slicer, not
for G-code viewer. Thus the callbacks for 3D Mouse were not registered
for and the 3D mouse did not work on Windows.
Fixed by calling the callback registration from the first execution
of the Idle function.
But now there is a problem with font scaling.
Function font.Scaled(val) return scaled system font from primary monitor.
That is why application's name and version has so strange scale.
* Changed some labels on buttons. The Dialog name shows a purpose now
* SaveDialog is called, when UnsavedChangesDialog is shown.
* Added prototype for the "exit" icon
+ Fixed layout for the "Machine limits" page
Splash Screen under OSX requires a call of wxYeild() for update.
But wxYield() furthers a case, when CallAfter() in CLI::run() was called at the wrong time, before some of the GUI was created.
So, there is workaround:
Parameters needed for later loads are encapsulated to GUI_App::AFTER_INIT_LOADS structure
and are used in GUI_App::AFTER_INIT_LOADS::on_loads which is called just ones after wxEVT_IDLE
+ Create controls only on the shown and active tab
+ Line class : deleted unused sizer
+ In GUI_Utils added TaskTimer class for the print a time of some task duration
+ BedShapeDialog:: activated options_groups
+ commented some unused code
