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
as the opengl context may not be ready on some platforms (Linux)
at the time the window gets its focus for the first time.
Changed the G-code preview invalidation to trigger when the print
gets invalidated. At that time the 3D path preview switches to the old
preview, if there is anything valid left.
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.
making it safe in case wxWidgets do not report supporting multisampling,
but the OpenGL context actually does and it leaves the multi-sampling enabled.
This then may in theory lead to incorrect picking by color.
Slic3r GUI not starting, error when using --gui (on linux)

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 lower memory consumption.
Rewrote the print path 3D preview to generate these indexed triangle / quad
sets, possibly with at least as possible duplication of vertices,
with a crease angle of 45 degrees, leading to maximum 8% overshoots
at the corners.
The shaders are initialized when the layer editing button is pressed
for the first time. If the initialization fails, a message box
is shown and the layer editing will stay disabled.
It is a bug, which was lingering around for a long time, only now
the buggy function is called at a time point, where it really hurts.
