Geometry shapes quality check

[yvanblanchard]

It would be very helpful to control and check quality of imported geometry, and display areas/points of defects with red dots (ex: very small faces of breps, that could lead to meshing issues).

@fougue I noticed that some "repairing" messages are triggered when importing STEP geometry. Are those fixing steps documented and customizable by final user ? (ex: minimum small faces area,..)
