fixes https://github.com/prusa3d/Slic3r/issues/672
The Intel HD Graphics hangs on the glFinish() call for some reason
with one particular graphics driver revision. Also the glFinish() call
was superfluous and it only may have had negative effect over the performance.
Both glFinish() and glFlush() were removed for performance reasons
where they were not needed, see
https://www.khronos.org/opengl/wiki/Common_Mistakes
re-enable them when the G-code preview is ready.
Resurrected the old logic to automatically switch to the tool preview
for a multi-material print, and to switch automatically to the feature
preview for a single material print.
as the GCode is generated outside of the Print class.
Exported the GCodePreviewData as GCode::PreviewData to Perl.
When exporting the G-code with a command line Slic3r,
the GCodeAnalyzer is now supressed for performance reasons.
Removed obsolete Perl module Slic3r::GUI::Plater::3DToolpaths.
merged "Use submenus for listing options in dropdown menu." #3905
thanks @alexrj
Adapted the "Use submenus" code to sort the menus in the same order
as they appear in the parameter tabs.
Slic3r GUI not starting, error when using --gui (on linux)
Implements https://github.com/prusa3d/Slic3r/issues/407
Shortcuts: Movement in 3D Space
Assignment of the camera shortcuts is clear from the menu accelerators.
Implements https://github.com/prusa3d/Slic3r/issues/406
Shortcuts: Rotate +/- 45 degrees
l/r keys rotate the object
Also changed the accelerators for adding / removing duplicates from
Ctrl++/- to plain +/-, from Ctrl-Del to plain Del,
and added an 's' key accelerator for uniform scaling.
for the Slic3r Prusa Edition.
Hopefully a fix of https://github.com/prusa3d/Slic3r/issues/258
by moving the 2D thumbnail generation to the main thread and
forcing the simple 2D convex hull for even the small objects.
If the "interface_shells" feature is disabled, the "ensure vertical wall thickness"
feature will not add full infill over internal shells.
Fixed some issues with delayed loading of 3d scenes.
