|Summary||0030971: Visualization - can Font_BRepFont generate composite curve to C1 rather than to C0?|
|Description||void Font_BRepFont::SetCompositeCurveMode (const Standard_Boolean theToConcatenate);|
Above method will generate composite curve to C0 if set the flag to true, it's no a good practice. In real application, C1 is more preferable than C0. Another reason is that C1 will good for later modeling algorithm base on font, such as extrusion, revolution, etc. C0 will fail the modeling algorithm in most cases.

|Test case number|
This flag within Font_BRepFont is an attempt to reduce geometric definition of the glyph shape.
Currently, it combines ALL curves within a glyph contour, therefore there is no reason to expect better continuity than C0.
It could be possible detecting smoothly connected segments within glyph curve and merge only them, but I have no idea if this actually happens in practice.
Patches are welcome.
||It's possible to split the composite spline curve at C0 point. This changes should not be hard.|
