I am sorry, but your proposed solution, to manually offset the pointer and knob in the gauge, is certainly not an adequate fix for the problem. Please note that the NorthEast quarter gauge is not the only quarter gauge that has this cropping problem. As seen below, the NorthWest has it too, as do the SouthEast and SouthWest gauges. Further, I would note that I have ensured that the Start and Sweep angles are all set appropriately for these gauges, and nothing seems to fix the cropping.
As you can see, not only is the pointer knob getting cropped, but so is the edge of the rim and the labels. This is happening for all quarter gauges, but it is most evident in the NorthWest gauge. It is obvious to me that the code that renders the gauge fails to add any extra padding to compensate for any of the elements of the gauge going beyond the edge of the initial square used to size the gauge. This is clearly a bug in the code, and should be addressed directly. Offering a solution by saying that I should be able to implement a custom pointer to manually offset the knob is a hack of a solution, and is not acceptable. This cropping should be in no way the default behavior of the gauge, and this needs to be fixed so that quarter gauges by default show all of the elements of the gauge without cropping them, without requiring any modifications or adding custom elements to the gauge.
