WIP to G-code export parallelization through pipelining:
GCodeProcessor is called during the G-code export,
the G-code is no more reopened and re-read, but it is pipelined
from the G-code generator.
GCodeViewer no more parses G-code just to extract line end positions.
Removed start_mapping_gcode_window(), void stop_mapping_gcode_window(),
they are no more needed.
Follow-up to ea4e9b35a3e2084325fbaed4c5bedf310bcdef3e
Win32 specific: Substitute slashes to back slashes in file paths
when loading model files (STLs, 3MFS ...)
1) Changed the name of the variable "brim_offset" to "brim_separation"
for clarity.
2) Added legacy conversion after loading an old 3MF that does not define
then new "brim_separation" variable: The "brim_separation" is being
filled in with the "elefant_foot_compensation" value to produce
equal brim separation to the old PrusaSlicer that saved that 3MF file.
reset timestamp to 1. This led to a bug where e.g. deleting painted facets
through the respective item in object list followed by possible other actions
and undo restored the painted facets from the time when the project was loaded.
I'm not sure if there was any other situation where this problem manifested.
Refuse outgoing during simlification.
Refuse start simplification when other Gizmo is active
Fix close after preview to revert changes
Allow change model for simplification
1) Slic3r::RuntimeError was replaced with ConfigurationError,
all exceptions thrown by the configuration layer are derived
from ConfigurationError.
2) When parsing configuration files, ConfigurationError is catched and
rethrown extended with the file name being parsed.
Note: When ProgressDialog has no-nullptr parent, then PrusaSlicer doesn't lose the focus at the end of model fixing,
but start to flickering during fixing of the big models.
Make is_converted_from_meters / is_converted_from_inches exclusive-or.
Maybe it would be better to make a single enum from the two booleans,
if they are exclusive-or?
This reverts commit d001195ebd2239ba21f31a908d1c146e7af03c08. It makes no sense,
reload from disk is used when the file has changed, which means the paint-on
data are possibly meaningless or even completely wrong (referencing
triangles that no longer exist)
