+ msw_rescale() is overridden for PrinterTab to rescale of all the option Pages and not just a respect to current print technology
+ A Setting of the option.width in PrintConfig is no need anymore
The two new config keys define a minimum vertical shell thickness.
The top shell thickness is calculated as a maximum of sum over
top_solid_layers * layer heights and top_solid_min_thickness,
the bottom shell thickness is calculated as a maximum of sum over
bottom_solid_layers * layer heights and bottom_solid_min_thickness.
The results of the formula above are shown at the Print parameter page
below the two new values to hint the user about the interaction
of the old versus new config values.
top_solid_min_thickness has no meaning if top_solid_layers is zero,
bottom_solid_min_thickness has no meaning if bottom_solid_layers is zero.
which now will be used for preset choosers on sidebar a preset tabs.
+ for BitmapCache class added m_scale used for correct scaling of SVG images on Retina displays
+ some code clearing from unused functions or function's parameters
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.
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.
improved utf8 compatibility of Tab::may_discard_current_dirty_preset(),
renamed "SLA Print Profile" / "SLA Material Profile" to just "Print Profile"
resp. Material Profile.
