getSVG puts placeholders in the generated SVG code and replaces them
afterwards with length values. With the changes of the previous commits
this seems not to be necessary anymore.
I replace them in a separate commit so this change can be reverted easily.
* Both properties are automatically added to old section planes
with the help of onDocumentRestored.
* A bit of style clean up to improve the readability of touched code lines.
* getSVG provides new style parameters for every kind of line:
V, V0, V1, H, H0, H1.
* Old line width parameters are removed. The style parameters
can be used instead.
* A style is a map container for svg attribute keys and values
(string, string).
* The Python interface is updated to offer the new style parameters
accordingly as a dict.
* Because there are many parameters on the function call now,
the Python interface supports keyword parameters.
* Update ArchSectionPlane to take advantage of the new style parameters.
This simplifies the code. String replacements could be removed
(done in a later commit).
* FeatureViewPy.cpp is – to my knowledge – the only function that used the
old line width parameters. I rewrote it to use the new style parameters.
When doing projection, there doesn't seem to have a reliable way of
knowing which edges are for inner holes. So we just suppress holes
altogether, and make it as outline only projection.
'feedrate' for normal move, and 'feedrate_v' for vertical only move if
not zero. Also added 'verbose' parameter to include complete cooridnate
and feedrate parameter in each motion GCode.
=======================================================
Introduction of construction points as fixed solver entities introduced this bug, as there was no specific code to check for points as they were by default construction.
