I'm trying to use the mouse to draw rectangles on a Picture indicator.
However, the mouse coordinates are not corresponding consistently to the Rectangle coordinates, and I can't seem to make sense of it.
Here's a video demonstrating the problem.

While you can't see whether I'm clicking or not, every short diagonal movement is a click-and-drag action.
(In one of them, I believe the rectangle it made was actually outside the picture).
Is there anything wrong with my code?
(Note:
I am using the Picture control, not at IMAQ image. This code is not intended to run on the cRIO, and probably won't be usable within the FRC Framework)
