Summary	0000471: Sketcher: trimming of a circle tangent to two parallel lines blocks the sketcher
Description	Create two horizontal lines, create a circle between, apply tangent constraints between the circle and both lines (one at a time), attempt to trim half a circle (either right or left) - the sketch is blocked with 'conflicting constraints'...
Additional Information	The culprit seems to be the fact that the trimming operation always adds a point on object constraint, whereas all it has to do in this case - is change the length/shape of the trimmed object. In addition (though might be an independent bug), after closing the sketch an reopening it, the 'Auto constraints' box which was previously unchecked, sets itself to 'checked'.
