I like your proposal very much

Acording to the wiki
http://www.freecadweb.org/wiki/index.ph ... nt_Tangent
There are four kinds of tangent constraints i will use the naming from there.
point-to-curve tangency includes a fix point to curve so it should not be nececery with any other constraint.
It might be better to consider both of theese constraints as being redundant. So if one is applied to another it might be posible to replace acording to this:
point-to-curve tangency + Fix Point Onto A curve -> point-to-curve tangency
Fix Point Onto A curve + point-to-curve tangency -> point-to-curve tangency
direct tangency + Fix Point Onto A curve -> point-to-curve tangency
Fix Point Onto A curve + direct tangency -> point-to-curve tangency
Aplying trim on this works now, so we only need to add a point-to-point constraint like this :
point-to-curve tangency + trim ->point-to-point tangency (witch includes coinsident)
