"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
using custom QT pen styles, the center and section lines look much
better.
With some math we are also able to control the middle position, thus
the centerlines will always look good, regardless of the size of an
object.
Also getting the section label size from the settings, so the font
size is controllable and not hardcoded.
Bonus: adding blank templates for the common paper sizes (as the
Drawing WB has them)
