Bug Description

If the image contains white space interrupted glyphs, the tracer wrongly interprets parts of glyph as a whole by itself.
There seems to be no way to circumvent this behavior from the GUI.
This could be corrected by adding a way to select and group parts of a glyph (e.g. pressing the shift key while clicking on the glyph's parts).
Attached by is an example image of such a situation. The same problem appears if using images of complex glyphs based on more then one part.

Another way to solve this maybe to add a user definable infra-glyphs space count value (in pixels). Glyphtracer should consider background pixels count to be space between characters only if the count exceeds this value.
In this case a Retrace button would be really useful.

A quick workaround is to manually draw an underline to the glyphs that get split up and then remove the extra line in Fontforge.
