Now all escaping required for the C++ code generation is done when the
.cpp/.h files are generated. Previously, only newlines were escaped
automatically. This was a) inconsistent and b) leaked c++ details into
the xml data.
In addition, the escaping is now done in one central place, harmonizing
the three previous implementations.
Pre-existing c++ escape sequences in the XML files have been replaced by
their literal equivalent so that the resulting python doc sting remains
unchanged.
Exposed to Python as new constructor parameters and
Rotation.toEulerAngles()
This function uses the code from OCCT
gp_Quaternion::Get/SetEulerAngles() to support all 24 possible
generalized euler rotation sequences. Call Rotation.toEulerAngles()
without argument to obtain all possible sequence types.
The new constructor accepts wanted directions of x,y,z axes of rotated
frame, and a priority string that affects how the vectors are made
perpendicular to each other.
Example - construct placement for sketch on XZ plane:
v = App.Vector
App.Rotation(v(1,0,0),v(0,0,1),v())
