bcad_height

If bcad_height it is specified, it is used instead of the standard attribute height to set a minimum height on any tile.

This allows to bypass small cosmetic problems in the BricsCAD DCL engine.
Since the BricsCAD DCL engine is implemented with WxWidgets, some small visual differences with an MFC based DCL engine cannot be avoided.

This is however rarely needed and normally concerns details only.

Applies to : any DCL tile can use bcad_height
