Creating the parsetab.py cache file in a system wide fixed location
(e.g. /tmp/parsetab.py) creates problems when a computer is used by
different users. Also the file is never removed, which is not very nice.
Caching provides hardly any benefit here, as it only takes milliseconds,
and may even be negated by the additional required filesystem operations.
Fixes (part of) #6315.
The original algorithm tried to use a heuristic to calculate which
objects should be shown or hidden, based on the object name. This commit
replaces that heurstic with a request for the list of root objects from
FreeCAD, which is then filtered to remove those that existed before the
import. Any descendant of those root objects is hidden, and the root
made visible, in keeping with the design of the CSG importer.
When not using the GUI, bounding box calculations can sometimes use the
B-spline represenation in OCCT, which can in some cases give incorrect
results. To correct for this, explicit calls to tessellate() are added
to ensure that the bounding box calculation uses the true shape, even if
the GUI is not running.
Fixes#4622 - OpenSCAD/OpenSCADTest/app/test_importCSG.py assertion failure
* [OpenSCAD] Fixes cut color while importing CSG
Fixes#4684.
For some reason colors of "base" and "tool" need to be set in order for the cut
to have colors as well, just like fuse and multifuse.
Also tidied up the relevant code portions a little.
Some testing might be needed.
* [OpenSCAD] Color settings for other booleans in importCSG
As per Keith's comments, this change extends recursive color setting to other
boolean features viz. `Part::Common` and `Part::MultiCommon`. Also possible to
add any other features needing the same treatment.
* Update importCSG.py
Remove unneeded parentheses and fix its/it's mixup

OCCT 7.3 did not work well when using a very large projection plane, so
this commit reduces the plane size to the minimum required for the cut
operation. It also performs some minor refactoring in anticipation of
the implementation of the true projection feature, and it removes the
last attempted fix, which proved unnecessary.
As pointed out in Issue #0004353 the OpenSCAD Workbench does not
correctly implement the angle parameter to rotate_extrude (it's a
relatively recent addition to OpenSCAD), nor does it attempt to do
anything with a specified $fn. This commit adds both features. To add
$fn handling, the code from the cylinder extrusion was mimicked,
allowing FreeCAD to create perfect, smooth representations when $fn
exceeds a user specified value in Preferences, but attempting to create
OpenSCAD's more discrete representation when using a lower $fn. Note
that this determination is made at creation time: if the user later
increases the segments parameter in the new object, it will remain
prismatic regardless of how high the value is made.
The existing implementation of resize() did not work, and used incorrect
scale factors. This commit implements a version that matches the results
obtained from within OpenSCAD.
