0026664: Triangulating a very small polygon fails

Parameter for adaptive computation of minimal 2D meshing precision added in BRepMesh_IncrementalMesh API.
Corresponding option -adaptive added in DRAW command

All meshing parameters are collected in structure, BRepMesh_FastDiscret::Parameters, which is now used to define and manipulate parameters of the algorithm.
