+ Added a calculation of a empty bitmaps inside presets in respect to em_unit (to avoid assert)
+ Added scaling for PrintHostDialogs and MsgDialog
+ some code refactoring
Fixed an issue, where deleting a profile did not correctly update
profile dependences, and deleting a profile would not test dirty status
of depending profiles, which would be switched thus user changes would be lost.
Fixed enabling / disabling the --default FFF-- / --default SLA-- profiles
when deleting the last printer profile.
Little refactoring (don't compare by strings but by symbolic names).
Making a copy of a profile - "Copy" suffix is added to a system profile.
Multi Material prints & soluble supports.
Disabled assert testing for the existence of "printer_technology" fields
as it triggers on loading of legacy AMF/3MF files.
Slicer crash when SLA printer is selected and printer profile is changed
First, there was a bug in the preset Tabs, where a "printer_technology"
was incorrectly queried on "print" and "filament"
(or "sla_print" and "sla_material") profiles.
Second, there was an unsafe "printer_technology" getter, which would add
the missing key to the config container when queried for.
