better fix (I think) for MSH2 and MSH3 : when -part_no_physicals is given, just copy the parent physicals in the partitioned entities

make MSH3 behave as before with partitioned meshes if no physicals are created for partitioned entities

PS: MSH3 is undocumented and will never be. MSH4 is the future :-)

put origin world coordinate at center viewport + make sure model does not move when changing rotation center

Partitioning fix

See merge request !166

make sure screen stay unchanged after any rotation center modification + origin of world coordinate at center of screen

Performance increase for many_holes benchmark

See merge request !164

backward compatibility of new partitioned meshes with old MSH2 format, when -part_no_physicals is set

make gmsh Bezier the same than OCC Bezier

See merge request !163

don't use %[0-9- ] with fscanf, as we cannot detect overflow - use fgets first, and sscanf afterwards

fixes crash in msh4 ASCII format for entities with many bounding entities

Part physicals and topology pro
